•

To minimize shock hazard, the instrument chassis must be connected to an electrical ground. Using the supplied three-conductor power cable ensures that the instrument can be firmly connected to the ac power source and electrical ground at a grounded power outlet. If using a 3-2 wire adapter be sure to connect the ground lead to earth ground.

•

Use the buddy system any time work involving active high voltage components is required. Turn

OFF the power before making/breaking any electrical connection. Regard any exposed connector, terminal board, or circuit board as a possible shock hazard. DO NOT replace any component or module with power applied.

•

If test conditions to live equipment are required, ground the test equipment before probing the voltage or signal to be tested.

•

Personnel working with or near high voltage should be familiar with modern methods of resuscitation.

•

DO NOT wear jewelry (rings, bracelets, metal watches, and/or neck chains) while working on exposed equipment. Be very cautious about using hand tools near exposed backplanes, bus bars, and/or power supply terminals. Use properly insulated tools. When making test connections to the power supply terminals and bus bars, use only insulated probe tips.

•

Verify that the instrument is set to match the available line voltage and the correct fuse is installed.

•

1. GENERAL INFORMATION:

IM-501

1-1 PURPOSE: This manual contains setup and operation information for the Aeroflex / Weinschel’s Model 8311-XX-

X-XN Series of SmartStep

Attenuator Units. The manual also provides component location, reference designators, part numbers, and nomenclature to identify all the assemblies and sub-assemblies of the Attenuator Unit.

1-2 SCOPE: This manual is to be used in conjunction with the operation and maintenance of a Model 8311-XX-X-XN

Series SmartStep™ Attenuator Unit. The manual also provides a description of each assembly; assembly parts list; block diagrams: and general maintenance procedures to maintain the instrument.

1-3 EQUIPMENT DESCRIPTION: Aeroflex / Weinschel’s Model

8311-XX-X-XN Series SmartStep Attenuator Units represents a new concept in programmable attenuation for bench test and subsystem applications. Standard Model 8311-XX-X-XN designs house and control various Weinschel Programmable Attenuator

Models (3200T, 150T, and 4200 Series) via front panel controls or standard communications interfaces including Ethernet and

RS-232 Serial. Special configurations also exists where the RF section is designed to specific customer requirements which can contain to multiple programmable attenuations used in conjunction with other coaxial devices such as switches, power combiners, directional couplers, and filters creating single or multi-channel subsystems.

1-4 USING THE MODEL 8310-XX-X-XN: The Model 8311-XX-X-XN Series provides front-panel and computer control for up to 12 channels of attenuation, RF switching, or other functions. The Model 8311-XX-X-XN combines the features of the Aeroflex / Weinschel 8210A Device Controller with a front panel user interface to form a flexible, easy to use solution. Most Model 8311-XX-X-XN Series are multi-channel configurations where RF signal is routed through either the front or rear mounted channel connector to a single or multiple Weinschel programmable attenuators thus creating a channel.

For specialized configurations refer to supplemental information in the front of this manual for details. Typically

Weinschel programmables are bi-directional and the RF signal can be applied to either Channel connector. Channels can be selected by selecting the front panel CHAN button. When selected, as indicated by the CHAN indicator, a new attenuation value may be entered using the INCR and DECR keys. The main display will show the current attenuation setting of the channel.

A new attenuation setting in dB may be entered using the INCR/DECR or ENTRY keys. The front panel STEP key allows the user to define the attenuation step size used by the INCR and DECR keys. Remember that the attenuation step size (resolution) is limited to the physical size of the internal attenuator cells. For example a 0-70 unit with 10 dB steps can only be adjusted in 10 dB increments but larger increments such as 20, 30, 40 dB can be set using this key.

The REL key allows the user to set relative mode for attenuators.

When turned on, the currently displayed attenuation value is used as a reference value from which the attenuation may be set. In this mode, attenuation values may be positive or negative from the reference setting. When REL is turned off, the display returns to the actual attenuation setting for the channel. Refer to Section 5 for more detailed information about the front panel keys and indicators. All Model 8311-XX-X-XN Series functions can also be controlled via standard communications interfaces including Ethernet and RS-232 Serial. Refer to Section 6 for bus setup and operating instructions when using the Model 8311-XX-X-XN Series in the remote mode.

Model 8311-XX-X-XN IM-501

3-3.1 POWER ENTRY MODULE ASSEMBLY: The Power Entry Module Assembly located on the rear panel contains a three-prong ac power input connector and a fuse drawer assembly (Figure 1). The Fuse Drawer Assembly contains the line voltage fuse (Weinschel P/N 052-1-1.5). The Model 8311-XX-X-XN uses a T 1.5A, 250 Vac fuse which is 5 x 20 mm in size. Refer to paragraph 6-4.1 for replacement of the fuse.

The AC Power Connector, located on the left side of XF1 (Figure 1), is a plug-type, prong insert connector with three conductors for connection of the power cord (P/N 068-21) to the Power Supply Assembly located within the Attenuator

Unit. This connector also grounds the chassis of the Attenuator Unit when the the ac power cord is connected to a grounded wall outlet. If necessary, use a three prong to two prong adapter and connect the adapter’s ground lead to the outlet plate retaining screw.

The Power ON/OFF Switch is located on the rear panel and in part of the Power Entry Module Assembly. Placing the

POWER ON/OFF switch in the ON position applies power to the instrument.

CAUTION

When applying an RF signal to the RF INPUT connector, DO NOT exceed the maximum allowable power level specifications of the Model 8310-XX-X-XN.

3-3.2. CHANNEL PORT CONNECTORS: A typical Model 8311-XX-X-XN Series Attenuator Unit contains 12 standard D holes on the front and rear panel allowing for single or multichannel configurations. Standard

Model 8311-XX-X-XN’s are supplied with two PLANAR CROWN

Type N connectors that can be mounted on the front or rear panel. These connectors provide a input and output port where various types of RF signals can be applied to the devices internally mounted in the Model 8311-XX-X-XN (Connector location specified by customer when ordering). Some special configurations could contain Aeroflex / Weinschel’s Model 1568 SMA

Panel Adapters or other types of crowns (see accessories for other types).

NOTE

The use of the PLANAR CROWN

connectors provide the user with easy exchange of connector types, which eliminates the need for adapters and other devices that would create additional insertion loss. This type of connector also provides quick removal and replacement of defective connectors.

The following paragraphs provide setup and general guidelines for operating the Model 8311-XX-X-XN Series

SmartStep Attenuator Unit and its different bus configurations. Also provided is a general description of the internal circuitry of the Model 8310-XX-X-XN.

Figure 2. Model 8311-XX-X-XN Series Front Panel

ENTRY keys: The numeric entry keys allow the user to directly enter numeric values. When using the keypad, values are not updated until the ENT (enter) key is pressed. The Minus (-) and CE (clear entry) functions may be accessed via first depressing the SHIFT key.

INCR & DECR : The INCR and DECR keys allow settings to be scrolled from their current value.

Unlike the ENTRY keys, the new setting is updated immediately without the use of the ENT key.

CHAN: Allows the selection of the current channel, as indicated by the CH1-CH4 indicators.

Repeated depressions of the CHAN key will select the next available channel. The main display will show the current setting of the channel. For configurations with 5 or more channels, selecting the

CHAN key will display the current selected channel in the main display. Channels are then selected via the INCR and DECR keys.

REL: This key control allows the use of a relative mode for attenuators, as indicated by the REL mode indicator. When turned on, the currently displayed attenuation value is used as a reference value from which the attenuation may be set. In this mode, attenuation values may be positive or negative from the reference setting. When REL is turned off, the display returns to the actual attenuation setting for the channel.

STEP: This key allows the user to change the attenuation step size used by the INCR and DECR keys. When turned on, as, indicated by the STEP indicator, the current step size is displayed in the main display, and a new value may be entered using the INCR/DECR or ENTRY keys. The step size may be set to any multiple of the intrinsic step size for the currently selected channel.

MENU: Invokes the menu functions. Menu selections may be made via the INCR and DECR keys.

(NOTE: menu functions are currently not implemented as of 3/8/99)

AUX1/AUX2: The function of these keys is user-programmable via remote operation. They invoke any currently defined AUX1 and AUX2 macros. Refer to the macro programming section for information on creating macro definitions.

LOCAL: This key places the Model 8311 in local operation mode, unless the key function has been overridden via an IEEE-488.2 local lockout or execution of the LOCKOUT command.

ADDR: This key displays the current IEEE-488.2 address. The address may be changed from the front-panel, however, the initial setting at power on is derived from the rear-panel address switch.

5. REMOTE OPERATION:

IM-501

The following paragraphs provide setup and general guidelines for operating the Model 8311 using an external controller.

5-1. COMMUNICATIONS INTERFACE: The unit provides for control via a number of interface methods, including

IEEE 488.2, RS232 serial, and 10/100 baseT Ethernet. Interface functions are split between two assemblies:

1). the main controller (generically referred to as the 8210A),

2). the ethernet control interface.

The 8210A is responsible for control of the RF devices, and handles GPIB and RS232 communications. The

Ethernet control interface utilizes a Lantronix XPort™ Ethernet to serial device server which allows the 10/100baseT

Ethernet network to communicate to the 8210A via the RS232 port.

A block diagram of the communications subsystem is shown below.

5-1.1 Operating Modes: The rear-panel RS232 port serves several functions, which are controlled via the 3-position

Mode Select Switch.

Serial Mode: This position allows the RS232 port to be directly connected to the serial port of the

8210A, effectively bypassing the XPort’s ability to control the unit via the Ethernet port. In this mode, the serial port settings are controlled via the internal DIP switch of the 8210A.

Aeroflex / Weinschel

Model 8311-XX-X-XN

Ethernet Mode: This position internally connects the serial port of the device server to the serial port of the 8210A, allowing for network control of the unit. In this mode, the external serial port is non-functional. The serial communication settings of the device server must be set to match that of the 8210A for proper operation.

IM-501

Console Mode: This position connects the RS232 port directly to the XPort device server. This mode allows the setup/configuration of the device server to be performed via the RS232 port. In this mode, serial communications are fixed at 9600 N81. For detailed information regarding operation, refer to the Xport Users Guide Chapters 5-8 (Setup Mode) and Chapter 11 (Monitor Mode).

5-1.2 Serial Port Setup: By default, the unit is shipped configured for 9600 baud, no parity, and 1 stop bit, with no handshaking required (9600N81). The rear-panel male DE-9 connector is configured as a DTE port (the same as a typical PC) with the following pinout:

Connection to another DTE device (ie a PC) requires the use of a null-modem cable to swap pins 2 and 3.

Communication settings for the 8210A are controlled via the internal Serial/GPIB Settings DIP switch located on the board (refer to the 8210A Manual IM-288), while the XPort serial configuration is set independently and can be done using a variety of methods. Refer to the Xport Users Guide for a detailed description of the available setup mode methods and options.

NOTE

If you wish to change the serial port operation, keep in mind that the settings must match in both places in order for the XPort to communicate successfully with the 8210A when used in the

Ethernet control mode.

5-1.3 Ethernet Setup: The network address of the XPort must be configured prior to use. There are several ways to assign an IP address to the Xport. A general overview is provided here. For more detailed information and links to video tutorials on performing many of these steps, refer to the information provided on the CD.

5-1.3.1 DeviceInstaller: The Lantronix DeviceInstaller is a Windows-based program that can be used to setup the

Xport. Of the methods presented here, this is the simplest. However, the DeviceInstaller relies on the Xport being set for DHCP. If a static IP has been previously assigned to the Xport, there is a high probability that the DeviceInstaller will not be able to see the Xport, especially if the IP or Gateway network settings do not match that of the PC currently being used. If that is the case, you will have to use one of the other methods outlined below.

To use the DeviceInstaller utility, first install it from the product CD or click on the link below to download the latest version of DeviceInstaller. http://ltxfaq.custhelp.com/app/answers/detail/a_id/644 a. Insert the product CD into your CD-ROM drive. b. View Readme.txt located in the Lantronix Xport CD files Rev2 folder. c. Select the desired DeviceInstaller and run the associated setup program within the folder. d. Respond to the installation wizard prompts. (When prompted to select an installation type, select Typical.)

IM-501 adapter, a message displays. Select an adapter and click OK. b. Click the Search icon and select the unit from the list of Lantronix device servers on the local network. c. Click the Assign IP icon. d. If prompted, enter the hardware address (on the product label) and click Next. e. Select Assign a specific IP address and click Next. f. Enter the IP address. The Subnet mask displays automatically based on the IP address; if desired, you may change it. On a local network, you can leave the Default gateway blank (all zeros). Click Next. g. Click the Assign button and wait several seconds until a confirmation message displays. Click Finish. h. Select the device from the main window list and select Ping from the Tools menu. The Ping Device dialog box shows the IP address of the selected unit. i. From the Tools menu, click the Ping button. The results display in the Status window. Click the Clear Status button to clear the window so you can ping the device again.

Note: If you do not receive “Reply” messages, make sure the unit is attached to the network properly and the IP address assigned is valid for the particular network segment you are working with. If you are not sure, check with your systems administrator. j. Click the Close button to close the dialog box and return to the main window.

5-1.3.2 Serial Port Login: To assign the IP address and other network settings using a serial connection: a. Connect a console terminal or a PC running a terminal emulation program to the rear-panel RS232 connector.

The default serial port settings are 9600 baud, 8 bits, no parity, 1 stop bit, no flow control. Set the rear-panel

Mode Select switch to the Console position. b. To enter Setup Mode, cycle the unit's power (power off and back on). After power-up, the self-test begins and the red Diagnostic LED starts blinking. You have one second to enter three lowercase ‘x’ characters.

Note: The easiest way to enter Setup Mode is to hold down the ‘x’ key at the terminal (or emulation) while powering up the unit. c. The display should be similar to:

MAC address 00204AC530DB

Software version V6.6.0.2 (080926) XPTEXE

Press Enter for Setup Mode

d. The Xport has a built-in timeout function, and you must press the ‘Enter’ key within three seconds to enter the

Setup Mode. If you do not, the Xport will timeout and display “?!?”, after which it will continue with the boot process and you will have to repeat Step 2. e. Select 0 (Server Configuration) and follow the prompts until you get to IP address. f. Enter the new IP address, subnet mask, and gateway (if applicable). g. Select 9 to save and exit Setup Mode. The unit performs a power reset.

Aeroflex / Weinschel

Model 8311-XX-X-XN IM-501

5-1.3.3 ARP and Telnet: If a serial port is unavailable, you can use the Address Resolution Protocol (ARP) method from UNIX and Windows-based systems to assign a temporary IP address.

To assign a temporary IP address:

a. On a UNIX or Windows-based host, create an entry in the host's ARP table using the intended IP address and the hardware MAC address of the Xport, which should be available on the rear-panel of the unit. Make sure that the intended IP is reachable with the current network settings of the host. The following example uses an

IP of 192.12.3.77. Substitute the desired address in it’s place, and the MAC address of the Xport in place of the 00:20:4a:xx:xx:xx

arp -s 191.12.3.77 00:20:4a:xx:xx:xx (Unix)

arp -s 191.12.3.77 00-20-4a-xx-xx-xx (Windows) b. Open a Telnet connection to port 1. The connection fails quickly, but the unit temporarily changes its IP address to the one designated in this step.

telnet 191.12.3.77 1 c. Open a Telnet connection to port 9999, and press Enter within three seconds to go into Setup Mode. If you wait longer than three seconds, the unit reboots and you will have to repeat Step 2.

telnet 191.12.3.77 9999 d. Select 0 (Server Configuration) and follow the prompts until you get to IP address. e. Enter the new IP address, subnet mask, and gateway (if applicable). f. Select 9 to save and exit Setup Mode. The unit performs a power reset.

5-1.3.4 DHCP: The unit ships with a default IP address of 0.0.0.0, which automatically enables DHCP. If a DHCP server exists on the network, it provides the unit with an IP address, gateway address, and subnet mask when the unit boots up.

The DeviceInstaller software can be used to search the network for the DHCP assigned IP address and add it to the list of devices retrieved.

NOTE

This DHCP address does not appear in the unit’s Setup Mode or in Web Manager. You can determine your unit’s DHCP-assigned IP address in Monitor Mode. When you enter Monitor Mode from the serial port with network connection enabled and issue the NC (Network Communication) command, you see the unit’s IP configuration.

5-1.3.5 AutoIP: The unit ships with a default IP address of 0.0.0.0, which automatically enables Auto IP within the unit. AutoIP is an alternative to DHCP that allows hosts to obtain an IP address automatically in smaller networks that may not have a DHCP server. A range of IP addresses (from 169.254.0.1 to 169.254.255.1) has been explicitly reserved for AutoIP-enabled devices. Do not use this range of Auto IP addresses over the Internet.

 If your unit cannot find a DHCP server, and you have not manually assigned an IP address to it, the unit automatically selects an address from the AutoIP reserved range. Then, your unit sends out a (ARP) request to other nodes on the same network to see whether the selected address is being used.

 If the selected address is not in use, then the unit uses it for local subnet communication..

 If another device is using the selected IP address, the unit selects another address from the AutoIP range and reboots. After reboot, the unit sends out another ARP request to see if the selected address is in use, and so on.

Aeroflex / Weinschel

Model 8311-XX-X-XN IM-501

AutoIP does not replace DHCP. The unit continues to look for a DHCP server on the network. If it finds a DHCP server, the unit switches to the DHCP server-provided address and reboots.

NOTE

If a DHCP server is found, but it denies the request for an IP address, the unit does not attach to the network, but waits and retries.

AutoIP can be disabled by setting the unit’s IP address to 0.0.1.0. This setting enables DHCP but disables AutoIP.

5-1.3.6 BOOTP: Similar to DHCP, but for smaller networks. Automatically assigns the IP address for a specific duration of time.

5-1.3.7 Device Server Setup: The Channel Configuration section of the Setup Mode is used to define how the serial port responds to network and serial communications when operating as a device server. See the Xport Users Guide

Chapter 7 (Setup Mode: Channel Configuration) section for more details on each of these entries. Some of the important settings in this section are:

Baudrate: This is the baudrate used by the Xport to communicate to the 8210A when in device server mode. This setting must match the rate used by the 8210A, and is typically 9600.

I/F (Interface) Mode: The Interface (I/F) Mode is a bit-coded byte entered in hexadecimal notation.

This setting controls the serial port settings of the device server, such as number of bits, parity, stop bits, etc. The default value for this parameter is 4C, which specifies RS-232C, 8-bit, No Parity, 1 stop bit.

Flow: Flow control sets the local handshaking method for stopping serial input/output. The default setting for this parameter is 00 (no flow control)

Port Number: The setting represents the source port number in TCP connections. It is the number that is used to establish a connection via the network interface. The default setting for this parameter is

10001. This number may have to be changed to match the user’s software. Certain ports are reserved and should not be used. Refer to the section in the Xport Users Guide for a detailed list.

Compatibility note: units previously mfg’d using the Lantronix MSS-LITE were set to communicate via port 3001

Connect Mode: Connect Mode defines how the unit makes a connection, and how it reacts to incoming connections over the network. Enter Connect Mode options in hexadecimal notation. The default setting is C0, which sets the following options:

Incoming Connection - Always Accept

Response - Nothing (quiet)

Active Startup - No active startup

5-1.3.8 Example Setup Using The Serial Port:

a. Set the rear-panel MODE SELECT switch to CONSOLE position. b. Open a terminal emulator. Set the PC serial port for 9600N81, no flow control. Serial port cable connections to a PC will require the use of a null-modem cable (DTE to DTE device). c. To access the Xport SETUP mode, you must enter three lowercase 'x' characters within one second after powering on the unit. The easiest way to enter Setup mode is to hold down the 'x' key, and power up the unit. d. Response should be::

MAC address 00204AC530DB

Software version V6.6.0.2 (080926) XPTEXE

Press Enter for Setup Mode

Aeroflex / Weinschel

Model 8311-XX-X-XN e. Pressing the 'Enter' key should display the SETUP mode settings:

NOTE

There is a timeout function built into the SETUP mode. If you do not press the 'Enter' key within 2-3 seconds of the signon message appearing, you will need to turn off the power and start again. If the timeout occurs, you will see the characters “?!?” displayed on the screen.

You should now be able to communicate with the device. To send commands, you can use the Windows Telnet application to open a connection to Port 10001 (the default serial device tunnel port)

C:\WINDOWS>telnet 10.100.103.49 10001

Characters that you type in the telnet window will be sent to the device. For example, typing “*IDN?” Should get a response similar to:

Weinschel, 8310, 001, V2.98

NOTE

By default, the controller does not echo received characters, so the telnet client must be set for

'local echo' in order to see the characters that you type. Optionally, you can send the command

“ECHO 1” to set the controller to echo received characters.

5-2. Serial Operation: The serial interface (RS232/RS422) provides a means of remotely programming the 8310 via external computer. The 8311-XXX-X-XN provides for user-selectable communications parameters via a DIP switch

(SW1), including baud rate, data format, and handshaking method. LED indicators are provided for transmit (TX) and receive (RX) activity. Selection between RS232/RS422 mode is controlled via an internal 4 position DIP switch SW2, which also provides for user-selectable 120 ohm terminations for the RS422 receiver lines. The RS422 mode transceivers are electrically compatible with RS485.

SW2 RS232 RS422

RS485

Description

Select On = Termination

Off = No Termination

Select On = Termination

Off = No Termination

On = RS232

Off = RS422

The data format includes a start bit, eight data bits, and one stop bit (N81). The Baud Rate may be set to

2400, 9600, 19200, or 34800. Parity selections include settings for None, Even, or Odd parity. Handshaking may be enabled, if desired, and the method may be set to either hardware (RTS/CTS) or software (XON/XOFF). For interactive terminal use, echoing may be enabled, in which the 8210A will echo all characters received back to the terminal.

All data and commands are encoded using the ASCII character set. The syntax for commands is the same as for GPIB operation, and uses the syntax structure defined by IEEE 488.2, with the exception of the command termination rules. Commands sent to the 6853may be terminated with either an ASCII CR (0x0D) or ASCII LF (0x0A) character. By default, all responses from the 6853are terminated in an ASCII CR/LF sequence (0x0D followed by

0x0A).

Software handshaking uses the XON/XOFF scheme in which an ASCII DC3 (0x13) character is transmitted by the receiver to indicate that data transmission should be halted (XOFF), and an ASCII DC1 (0x11) character is transmitted to indicate that data transmission may continue (XON). Hardware handshaking utilizes the RTS and CTS lines. When the RTS output signal is asserted true, the unit is ready for data. This signal should be connected to the external computer's CTS input signal, so that when the receiver is ready, the transmitter may send data. When the unit is not ready for data, it unasserts the RTS signal, halting data transmission. Likewise, the unit monitors the CTS input signal during data transmission, halting transmission if the external computer unasserts it's RTS signal. In addition, the 6853unasserts the RTS signal while command execution is in progress.

For those systems incorporating local front panel controls, the serial port can lockout local users, providing a Remote/

Local function similar to that of GPIB operation.

5-3. Status Reporting

The 6853 implements the 488.2 Status Reporting Structure, which utilizes the IEEE488.1 status byte with additional data structures and rules. The Status Byte Register can be read with either a serial poll (IEEE-488 operation only) or the *STB? common query command. The Service Request Enable Register (SRE) allows the user to select which bits in the Status Byte Register may cause service requests. A bit value of one indicates that the corresponding event is enabled, while a bit value of zero disables an event. The Service Request Enable Register may be accessed with the *SRE and *SRE? common commands. The Status Byte Register may be cleared with the

*CLS common command, with the exception of the MAV bit, which is controlled by the operation of the Output Queue.

The SRE Register is set to 0 at power-on, disabling all events.

Request Service: This bit, if set, indicates that the device is asserting the SRQ signal.

Event Status Bit: This bit is true when an enabled event in the Event Status Register is true.

Message Available: This bit is true when there is valid data available in the output queue.

Error/Event Queue: This bit is true when there is Error/Event data available in the

Error/Event queue.

The Standard Event Status Register is used to report various IEEE 488.2-defined events. The register contents may be accessed with the *ESR? command. An Event Status Enable Register allows the user to select which bits in the ESR that will be reflected in the ESB summary message bit of the Status Byte Register. The Event

Status Enable Register may be accessed with the *ESE and *ESE? common commands. The Event Status Register is cleared by an *ESR? query or *CLS common command. The ESE Register is set to 0 at power-on, disabling all events.

Model 8311-XX-X-XN IM-501

The Status Reporting Registers may be used for serial communications, with certain limitations. The Status

Byte Register can only be read via the *STB? query command, as the comm port does not provide for a serial poll operation. Also, as data in the Output Queue is sent automatically during serial operation, the MAV message available bit in the STB serves no purpose.

5-4. GENERAL SYNTAX STRUCTURE: The following paragraphs outline the general syntax and command structure for the Model 6631. This structure is common to all bus flavors of the Model 6631.

NOTE

In the descriptions that follow, the term whitespace is used to define a sequence of one or more combinations of ASCII Space (20h), Carriage return (0Dh), or

Tab (09h) characters.

5-4.1 SYNTAX OF QUERIES: A query message unit is made up of a query header ending in an ASCII question mark character ’?’ (3FH), followed by optional whitespace, and ended by a program message terminator. To form a multiple query, separate the individual program message units with a semicolon.

Examples :

"ATTN?"

"ASSIGN?" b. Multiple Query Commands:

"ATTN?; ASSIGN?"

5-4.2 SYNTAX OF COMMANDS: A command message unit is made up of a command header, optionally followed by an argument and units, and ended by a program message terminator. If multiple commands are made on the same program line, separate the individual command messages with a semicolon.

Arguments - The 6853supports a variety of argument types that can be used in program commands.

These types are:



Character Program Data



Integer Numeric Program Data



Real Numeric Program Data

Each data type has its own rules of syntax. The following paragraphs provide the syntax rules for each of the argument types listed above.

Character Program Data-This data type is comprised of the set of printable ASCII characters (excluding those used as delimiters). Character program data represents alpha or alphanumeric strings. The use of alpha characters is case-insensitive. If the first character of the string is not an alpha character, then the string must be delimited with either the ASCII single-quote (’) or double-quote (") character in order to distinguish the string from a numeric data type.

Examples:

ATTEN1

"150T"

Integer Numeric Program Data-This data type is used to represent integer, binary, or hexidecimal numeric information, all of which may be used interchangeably. Integer data is comprised of the numeric digits ’0’-’9’, binary data is comprised of the digits ’0’ and ’1’ preceded by the characters ’#B’, and hexidecimal data is comprised of the digits ’0’-’9’, and the letters ’A’-’F’, preceded by the characters ’#H’ or the C language style prefix ’0x’.

Examples:

123 (integer)

#H55 (hex)

0xAA (hex)

#B1010 (binary)

Aeroflex / Weinschel

Model 8311-XX-X-XN IM-501

Real Numeric Program Data-This data type includes decimal numbers containing a sign, decimal point, and/or an exponent. The format is as follows: [sign]digits[.[digits][E[sign]digits]]

Examples: 2

2.5

-35.25E+2

In the command descriptions that follow, argument types are also described using the following additional conventions to indicate the relative size of the parameter: byte word int8 int16 int32 string

- used to indicate an 8-bit unsigned integer

- used to indicate a 16-bit unsigned integer

- 8-bit integer

- 16-bit integer

- 32-bit integer

- character data, including the max number of characters allowable.

(i.e., string8 has a max of 8 chars)

5-4.3 OUTPUT DATA FORMAT: Output data from the Model 6853 consists of a series of ASCII digits and message strings, terminated with an ASCII Line-Feed character (0AH), in response to a program message that contains one or more query commands. In the case of multiple query commands in the same program message, the data resulting from each of the individual message units will be separated by an ASCII comma (2CH) character.

5-4.4 NOTATIONAL CONVENTION.

[ ] Brackets indicate optional arguments or parameters.

{ } One and only one of the enclosed entries must be selected unless the field is also surrounded by brackets, in which case it is optional.

... Ellipses indicate that the preceding argument or parameter may be repeated.

[,...] The preceding item may be repeated, but each repetition must be separated by a comma.

6. MAINTENANCE:

IM-501

The following paragraphs provide general inspection and maintenance guide-lines for the Model 8310-XXX-

XN Attenuator Unit.

6-1. INSPECTION: Perform a visual inspection in conjunction with the maintenance activities schedule when a malfunction is suspected, or whenever an assembly is removed or replaced.

6-2. PREVENTIVE MAINTENANCE: While the 8310 requires very little preventive maintenance, it should not be subjected to physical abuse, severe mechanical shock, high humidity, or operating temperatures outside the specification range. The instrument should be kept free of excessive dirt and dust, since these can interfere with connector functions and with normal heat dissipation. For cleaning instructions refer to paragraph 6-3 (special cleaning instructions). The following paragraphs provide the preventive maintenance that is to be performed on the

Unit.

Care should be taken to prevent strain on the interconnecting cables, since damage here may not always be apparent. Occasionally check the external cables and connectors for signs of cracked insulation and/or bent or worn pins. Tests show that connectors must be clean for accuracy and stability. This requires an inspection and cleaning of each connector immediately before use. For connector cleaning instructions, refer to paragraph 6-3. When cleaning precautions are observed regularly, connectors can maintain their stability for over several thousand connection cycles. Refer to Appendix A for more information about cables and connectors.

6-3. SPECIAL CLEANING INSTRUCTIONS: The cleaning procedures for 8310 are divided into five general groups: microwave coaxial cable assemblies, circuit card and modules; machined surfaces and hardware, chassis cleaning, and connector cleaning.

6-3.1. MICROWAVE COAXIAL CABLE ASSEMBLIES: Appendix A (located at the end of this manual) provides all the necessary procedures for care, cleaning, and handling of microwave coaxial cable assemblies.

6-3.2 CIRCUIT CARDS AND MODULES: A protective coating is applied to circuit cards for protection from moisture, arcing, short-circuiting, and abrasion. To remove light dirt from circuit cards and modules proceed as follows:

CAUTION

 DO NOT use a nylon bristle brush in the solvent as the bristles may dissolve and cause damage to the circuit card or component.

 DO NOT use ultrasonic cleaning on parts or assemblies containing electrical or electronic components.

 DO NOT bend pins of electrical connectors when using fiber-bristle brush. a. Briskly brush isopropyl alcohol onto area to be cleaned with fiber-bristle brush. b. Carefully remove residue with a clean lint-free cloth and repeat step "a" as a rinse.

WARNING

Compressed air used for cleaning and/or drying can create airborne particles that may enter the eye. Goggles/ faceshields should be worn. DO NOT direct air stream towards self or other personnel. Pressure should be restricted to a maximum 15 psi to avoid personal injury. c. When parts are thoroughly clean, dry parts using 5 psi of clean moisture free compressed air or preferably dry nitrogen (pressurized spray will work well).

Aeroflex / Weinschel

Model 8311-XX-X-XN IM-501

6-3.3 MACHINED SURFACES AND HARDWARE: To remove light dirt and dust from mechanical parts such as castings, covers and other hardware proceed as follows:

WARNING

Compressed air used for cleaning and/or drying can create airborne particles that may enter the eye. Goggles/ face-shields should be worn. DO NOT direct air stream towards self or other personnel. Pressure should be restricted to a maximum 15 psi to avoid personal injury.

CAUTION

 Under no circumstances use a wire brush, steel wool, or abrasive compound. Using these items will cause extensive damage to the instrument's surface.

 DO NOT use a nylon bristle brush in solvent as the bristles may dissolve and cause damage to the circuit card or component. a. Use 5 psi of clean, moisture-free compressed air or preferably dry nitrogen to blow loose dirt and dust from surface of item. b. Briskly brush isopropyl alcohol onto area to be cleaned with a fiber-bristle brush. c. Remove residue with lint-free cloth and repeat step "b" as a rinse. d. When parts are thoroughly clean, dry parts using 5 psi of clean, moisture-free compressed air or preferably dry nitrogen. e. Clean smaller mechanical parts or hardware by dipping into a container of isopropyl alcohol. Remove dirt by brushing with fiber-bristle brush after parts have been immersed for several hours. f. Remove parts from isopropyl alcohol and rinse by immersing into a different container of isopropyl alcohol. g. When parts are thoroughly cleaned, dry parts using 5 psi of clean, moisture-free compressed air or preferably dry nitrogen.

6-3.4 CHASSIS CLEANING: Clean chassis using a lint-free cloth moistened with water and mild detergent. For harder to clean areas, such as inside corners of chassis, use a vacuum cleaner.

6-3.5 CONNECTOR CLEANING: Where small amounts of rust, corrosion, and/or oxide deposits are present on connectors, clean externally with a soft-bristle brush, aluminum wool, or internally with an acid brush; then wash with a non-corrosive solvent. MIL-C-83112 is recommended. Exercise care to ensure no metal filing or residue remains inside the connector and the connector is thoroughly dry. Where rust, corrosion, and/or oxide deposits are present in large quantities, replace the connector.

7. REPLACEABLE PARTS LIST:

IM-501

This section lists and describes the parts located in the Model 8310-XXX-XN Programmable Attenuator Units

(P/N 193-730X-X). The Replaceable Parts Lists (RPL) is intended for use in identifying, locating, and requisitioning assemblies and components for the Model 8310-XXX-XN.

7-1 UNDERSTANDING REFERENCE DESIGNATORS: All assemblies and electrical parts are identified by standard reference designators (resistors R1, for example). Reference designators are used in parts lists and on parts identification drawings. The title of a parts list or drawing contains the reference designator or the assembly or subassembly to which it applies. The designators in the parts list, as a prefix, but omitted from the list to make it easier to locate a specific part. To complete a reference designator in a parts list, precede the designator for the specific part (DS1, for example) with the designator in the title (A6, for example) to form a complete reference designator for the part (in this case, A6DS1).

7-2 ORDERING INFORMATION: When ordering parts from Aeroflex / Weinschel, please include the following information:

 Aeroflex / Weinschel part number.

 Description of the component or part.

APPENDIX A

CARE AND HANDLING OF MICROWAVE COAXIAL

CABLE ASSEMBLIES

A-1 CARE AND HANDLING OF ASSEMBLIES.

To en su re accur ate measu remen ts an d op timal performance of Weinschel products, the microwave coaxial cable assemblies used in system and test setups must be properly used and maintained. Proper connections, routine inspection of all cables, and cleaning of the connectors are extremely important procedures which can prolong the longevity and accuracy of equipment.

A-2 CABLE INSPECTION.

Routinely check external cables for signs of cracked insulation, dents, twists, flattening, signs of jacket abrasion, or other signs of abuse. Wrinkles in the jacket indicate that the minimum bend radius has been exceeded. Most often, this occurs near the marker tubes and connectors.

Also inspect the connector interfaces for the following:

•

Bent pins (male).

•

Bent or missing tines (female).

•

Worn or chipped plating.

•

Damaged or displaced dielectric inserts.

•

Thread damage.

•

Folded or mushroomed outer interface rims.

•

Mushroomed pin shoulders (male) or tine ends

(female).

•

Score lines on pins and outer interface rims visible to the unaided eye.

•

Recessed or protruding pins.

It is advisable to clean the connectors prior to inspection to make subtle damage more apparent. If any of the above is noted, replace the assembly before its further use results in equipment damage. Also inspect the mating connectors for similar damage.

Inspect the connector interface for signs of debris. Debris may be in the form of:

•

Plating chips or other metal particles.

•

Dust or dirt.

•

Oily films.

•

Other miscellaneous foreign particles.

If signs of debris are present, clean the connector interface as directed in Paragraph A-6.

A-3 MAKING INITIAL CONNECTIONS.

Exercise caution when mating cables. Poor connections lead to poor system performance. They can also damage not only the cable assembly, but more significantly, front or rear panel connectors on the equipment itself which may be more difficult to repair.

A-3.1

ALIGNING CONNECTORS.

Align the center lines of two connectors before actual mating. Male retaining nuts contain a small amount of necessary play which may make it possible to mate the threads without the pins being properly aligned. Pin misalignment can damage pins and dielectric inserts.

A-3.2

MATING CONNECTORS.

Gen t ly mate th e connectors by hand, taking care not to force the coupling nut at the slightest resistance. It is often possible to feel whether or not the pins are mated. If the coupling nut is difficult to turn, either the pins are not mated, the coupling nut is cross-threaded, or one of the connectors has been damaged by excess torque.

Never hold a male connector coupling nut stationary while screwing a female connector into it. This rotation can erode the plating and damage both the outer interface rim as well as the pin. If the pins become locked, serious damage can result to both the equipment and the cable assembly.

A-4 ENSURING PROPER CONNECTOR TORQUE.

A-4.1

OVERTORQUING.

Once connectors have been properly mated, apply only the proper amount of torque.

Overtorquing damages both connectors involved. Also, a connector which has been damaged by overtorquing, in turn, damages every connector to which it is subsequently mated.

It usually leads to poor system performance as well.

Overtorque can cause:

•

Bent pins.

•

Recessed or protruding pins.

•

Recessed or protruding dielectrics.

•

Chipped plating.

•

Damaged coupling threads.

•

Coupling nut retaining ring damage.

•

Mushroomed outer interface shells.

•

Mushroomed pin shoulders.

HEX-NUT TYPES.

also causes overtorque.

A-4.3

KNURLED NUTS.

T ig h ten co nn ector s with knurled nuts by hand. If this does not provide sufficient tightness use a hex-nut connector and torque wrench instead.

Never use pliers to tighten a connector. Table A-1 recommends torque specifications for the various types of connectors.

To mate a connector of the hex-nut type, always use a torque wrench set to the correct torque value. Tighten the connector slowly until the wrench snaps. Tightening too quickly can cause the wrench to exceed its set limit. Do not snap the wrench more than once as this

A-5 PROPER CABLE HANDLING.

Never exceed the minimum bend radius specified for a cable. Guard against tight bends at the end of connector strain relief tubing, or at the ends of marker tubing where they may be less noticeable. Although cable bend may seem slight, the actual radius of the bend at the point of angular departure may be far smaller than the acceptable radius.

Never pinch, crush or drop objects on cable assemblies.

Also, do not drag a cable over sharp edges as this will pinch it and cause it to exceed the minimum bend radius.

Never use a cable assembly to pull a piece of equipment.

Cables and connectors are not designed to support or move equipment.

A-5.1

SECURING CABLES.

Use toothed, rubber-lined

"P-clamps" to hold cables in place. If it is necessary to use tie-wraps, use the widest possible wrap and the lowest setting on the gun to ensure the minimum pressure on the cable.

A-5.2

STORING CABLES.

W he n st or ing cab les, minimize cable "set" by coiling them in large diameters (1 or

2 feet). Unroll the cable properly when it is ready to be used; do not pull the loops out hastily. Similarly, re-roll them when storing them away again.

A-6

CLEANING CONNECTOR INTERFACES.

Use the following guidelines in cleaning connector interfaces: a. Do not use chlorinated solvents including common tap water. These solvents are extremely penetrating and sometimes ruin otherwise good devices and assemblies.

b. Moisten a cotton swab with isopropyl alcohol. Roll the swab on a paper towel to remove excess. c. Use the moistened cotton swab to wipe away debris.

Do not try to dissolve the debris by overwetting the swab.

d. Repeat the cleaning process using additional swabs as necessary. If metallic particles are embedded in the dielectric, use an eyeglass and a sharp pick in an attempt to dislodge them. Swab again. e. When satisfied that the interfaces are clean, blow them dry with dry compressed air, or preferably dry nitrogen

(pressurized spray cans work well). Do not use breath. f. Clean the mating connectors. These may be the source of the debris.
