Power cord for the United Kingdom
When using the function generator in the United Kingdom, make sure the power cord meets the following safety instructions.
NOTE: This lead/appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with the following code:
Green/ Yellow:
Blue:
Earth
Neutral
Brown: Live (Phase)
As the colours of the wires in main leads may not correspond with the coloured marking identified in your plug/appliance, proceed as follows:
The wire which is coloured Green & Yellow must be connected to the Earth terminal marked with either the letter E, the earth symbol or coloured
Green/Green & Yellow.
The wire which is coloured Blue must be connected to the terminal which is marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the terminal marked with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment or contact the supplier.
This cable/appliance should be protected by a suitably rated and approved
HBC mains fuse: refer to the rating information on the equipment and/or user instructions for details. As a guide, a cable of 0.75mm
2
should be protected by a 3A or 5A fuse. Larger conductors would normally require
13A types, depending on the connection method used.
Any exposed wiring from a cable, plug or connection that is engaged in a live socket is extremely hazardous. If a cable or plug is deemed hazardous, turn off the mains power and remove the cable, any fuses and fuse assemblies. All hazardous wiring must be immediately destroyed and replaced in accordance to the above standard.

ODULATION
The MFG-2000 Series Multi Channel Function
Generators are able to produce AM, ASK, FM, FSK,
PM, PSK, PWM and SUM modulated waveforms.
In addition the MFG-2000 can also produce swept and burst mode waveforms. Depending on the type of waveform produced, different modulation parameters can be set. Only one modulation mode can be active at any one time. The function generator also will not allow sweep or burst mode to be used with AM/FM. Activating a modulation mode will turn the previous modulation mode off.

When burst mode is selected, any modulation or sweep modes will be automatically disabled. If no settings have been configured, the default settings for output amplitude, offset and frequency are used.
Burst Modes
Burst mode can be configured using Triggered (N Cycle mode) or
Gated mode. Using N Cycle/Triggered mode, each time the function generator receives a trigger, the function generator will output a specified number of waveform cycles (burst). After the burst, the function generator will wait for the next trigger before outputting another burst. N Cycle is the default Burst mode. Triggered mode can use internal or external triggers.
The alternative to using a specified number of cycles, Gated mode uses the external trigger to turn on or off the output. When the
Trigger INPUT signal is high, waveforms are continuously output.
When the Trigger INPUT signal goes low, the waveforms will stop being output after the last waveform completes its period. The

Command Syntax
Compatible standard
IEEE488.2, 1992 (fully compatible)
SCPI, 1994 (partially compatible)
Command Tree
The SCPI standard is an ASCII based standard that defines the command syntax and structure for programmable instruments.
Commands are based on a hierarchical tree structure. Each command keyword is a node on the command tree with the first keyword as the root node. Each sub node is separated with a colon.
Shown below is a section of the SOURce[1|2|3|4] root node and the :PM and :PULSe sub nodes.
Command types
Commands can be separated in to three distinc types, simple commands, compound commands and queries.
Simple
A single command with/without a parameter
Example *OPC
Compound
Example
Two or more commands separated by a colon (:) with/without a parameter
SOURce1:PULSe:WIDTh
218
REMOTE INTERFACE
Query
Example
A query is a simple or compound command followed by a question mark (?). A parameter (data) is returned. The maximum or minimum value for a parameter can also be queried where applicable.
SOURce1:FREQuency?
SOURce1:FREQuency? MIN
Command forms
Commands and queries have two different forms, long and short. The command syntax is written with the short form of the command in capitals and the remainder (long form) in lower case.
long long
SOURce1:DCOffset
short short
The commands can be written in capitals or lowercase, just so long as the short or long forms are complete. An incomplete command will not be recognized.
Below are examples of correctly written commands:
LONG SOURce1:DCOffset
SOURCE1:DCOFFSET source1:dcoffset
SHORT SOUR1:DCO sour1:dco

Square Brackets []
Commands that contain squares brackets indicate that the contents are optional. The function of the command is the same with or without the square bracketed items. Brackets are not sent with the command.
For example, the frequency query below can use any of the following 3 forms:
SOURce1:FREQuency? [MINimum|MAXimum]
Braces {}
Angled Brackets
<>
Bars |
Parameters
SOURce1:FREQuency? MAXimum
SOURce1:FREQuency? MINimum
SOURce1:FREQuency?
Commands that contain braces indicate one item within the braces must be chosen. Braces are not sent with the command.
Angle brackets are used to indicate that a value must be specified for the parameter. See the parameter description below for details. Angled brackets are not sent with the command.
Bars are used to separate multiple parameter choices in the command format.

Separators
MFG-2000 Series User Manual
Space
Colon (:)
A space is used to separate a parameter from a keyword/command header.
A colon is used to separate keywords on each node.
Semicolon (;)
A semi colon is used to separate subcommands that have the same node level.
Colon +
Semicolon (:;)
For example:
SOURce[1|2|3|3RF]:DCOffset?
SOURce[1|2|3|3RF]:OUTPut?
SOURce1:DCOffset?;OUTPut?
A colon and semicolon can be used to combine commands from different node levels.
Comma (,)
For example:
SOURce1:PM:SOURce?
SOURce:PULSe:WIDTh?
SOURce1:PM:SOURce?:;SOURce:
PULSe:WIDTh?
When a command uses multiple parameters, a comma is used to separate the parameters.

Apply Commands
The APPLy command has 5 different types of outputs (Sine, Square,
Ramp, Pulse, Noise, ). The command is the quickest, easiest way to output waveforms remotely. Frequency, amplitude and offset can be specified for each function.
As only basic parameters can be set with the Apply command, other parameters use the instrument default values.
The Apply command will set the trigger source to immediate and disable burst, modulation and sweep modes. Turns on the output commandOUTPut[1|2|3|3RF|pulse] ON. The termination setting will not be changed.
As the frequency, amplitude and offset parameters are in nested square brackets, amplitude can only be specified if the frequency has been specified and offset can only be specified if amplitude has been set. For the example:
SOURce[1|2|3|3RF|pulse]:APPLy:SINusoid [<frequency>

For the output frequency, MINimum, MAXimum and DEFault can be used. The default frequency for all functions is set to 1 kHz. The maximum and minimum frequency depends on the function used. If a frequency output that is out of range is specified, the max/min frequency will be used instead. A “Data out range error will be generated” from the remote terminal.

MFG-2000 Series User Manual
Output
Amplitude
When setting the amplitude, MINimum,
MAXimum and DEFault can be used. The range depends on the function being used and the output termination (50Ω or high impedance). The default amplitude for all functions is 100 mVpp (50Ω).
If the amplitude has been set and the output termination is changed from 50Ω to high impedance, the amplitude will double. Changing the output termination from high impedance to
50Ω will half the amplitude.
Vrms, dBm or Vpp units can be used to specify the output unit to use with the current command. The
VOLT:UNIT command can be used to set the units when no unit is specified with the Apply command. If the output termination is set to high impedance, dBm units cannot be used. The units will default to Vpp.
The output amplitude can be affected by the function and unit chosen. Vpp and Vrms or dBm values may have different maximum values due to differences such as crest factor. For example, a
5Vrms square wave must be adjusted to 3.536
Vrms for a sine wave.
DC Offset voltage
The offset parameter can be set to MINimum,
MAXimum or DEFault. The default offset is 0 volts. The offset is limited by the output amplitude as shown below.
|Voffset| < Vmax – Vpp/2
If the output specified is out of range, the maximum offset will be set.
236
REMOTE INTERFACE
The offset is also determined by the output termination (50Ω or high impedance). If the offset has been set and the output termination has changed from 50Ω to high impedance, the offset will double. Changing the output termination from high impedance to 50Ω will half the offset.

Description
Source Specific
Command
The SOURce[1|3|4]:AMPLitude command sets the output amplitude for the selected channel. The query command returns the current amplitude settings.
Note
The maximum and minimum amplitude depends on the output termination. The default amplitude for all functions is 100 mVpp (50Ω). If the amplitude has been set and the output termination is changed from 50Ω to high impedance, the amplitude will double. Changing the output termination from high impedance to 50Ω will half the amplitude.
Syntax
The offset and amplitude are related by the following equation.
|Voffset| < Vmax – Vpp/2
If the output termination is set to high impedance, dBm units cannot be used. The units will default to
Vpp.
The output amplitude can be affected by the function and unit chosen. Vpp and Vrms or dBm values may have different maximum values due to differences such as crest factor. For example, a
5Vrms square wave must be adjusted to 3.536
Vrms for a sine wave.
The amplitude units can be explicitly used each time the SOURce[1|2|3|3RF|pulse]:AMPlitude command is used. Alternatively, the VOLT:UNIT command can be used to set the amplitude units for all commands.

Sets or queries the peak frequency deviation of the modulating waveform from the carrier waveform.
The default peak deviation is 100Hz.
The frequency deviation of external sources is controlled using the ±5V MOD INPUT terminal on the rear panel. A positive signal (>0~+5V) will increase the deviation (up to the set frequency deviation), whilst a negative voltage will reduce the deviation.
Note
The relationship of peak deviation to modulating frequency and carrier frequency is shown below.
Peak deviation = modulating frequency – carrier frequency.
266
REMOTE INTERFACE
Syntax
Parameter
Example
The carrier frequency must be greater than or equal to the peak deviation frequency. The sum of the deviation and carrier frequency must not exceed the maximum frequency for a specific carrier shape. If an out of range deviation is set for any of the above conditions, the deviation will be automatically adjusted to the maximum value allowed and an “out of range” error will be generated.
For square wave carrier waveforms, the deviation may cause the duty cycle frequency boundary to be exceeded. In these conditions the duty cycle will be adjusted to the maximum allowed and a
“settings conflict” error will be generated.

Burst Mode Commands
Burst Mode Overview
Burst mode can be configured to use an internal trigger (N Cycle mode) or an external trigger (Gate mode) using the Trigger INPUT terminal on the rear panel. Using N Cycle mode, each time the function generator receives a trigger, the function generator will output a specified number of waveform cycles (burst). After the burst, the function generator will wait for the next trigger before outputting another burst. N Cycle is the default Burst mode.
The alternative to using a specified number of cycles, Gate mode uses the external trigger to turn on or off the output. When the
Trigger INPUT signal is high*, waveforms are continuously output
(creating a burst). When the Trigger INPUT signal goes low*, the waveforms will stop being output after the last waveform completes its period. The voltage level of the output will remain equal to the starting phase of the burst waveforms, ready for the signal to go high* again.
*assuming the Trigger polarity is not inverted.
Only one burst mode can be used at any one time. The burst mode depends on the source of the trigger (internal, external, manual) and the source of the burst.

Select Waveform
Frequency, amplitude and offset
Load Waveform
Data
2. Use the APPLy command to select frequency, amplitude and DC offset. Alternatively, the
FUNC, FREQ, AMPl, and DCOffs commands can be used.
3. Waveform data (1 to 16384 points per waveform) can be downloaded into volatile memory using the DATA:DAC command.
Binary integer or decimal integer values in the range of ± 8191can be used.

SOURce[1|2|3]:FUNCtion USER
Description
Source Specific
Command
Use the SOURce[1|2|3]:FUNCtion USER command to output the arbitrary waveform currently selected in memory. The waveform is output with the current frequency, amplitude and offset settings.
Syntax
Example
SOURce[1|2|3]:FUNCtion USER
SOUR1:FUNC USER
Selects and outputs the current waveform in memory.
DATA:DAC
Description
Source Specific
Command
The DATA:DAC command is used to download binary or decimal integer values into memory using the IEEE-488.2 binary block format or as an ordered list of values.
Note
The integer values (±8192) correspond to the maximum and minimum peak amplitudes of the waveform. For instance, for a waveform with an amplitude of 5Vpp (0 offset), the value 8192 is the equivalent of 2.5 Volts. If the integer values do not span the full output range, the peak amplitude will be limited.
The IEEE-488.2 binary block format is comprised of three parts:
# 7 2097152
1. Initialization character
(#)
1 2 3
2. Digit length (in ASCII) of the number of bytes
3. Number of bytes
309
MFG-2000 Series User Manual
Syntax
Parameter
Example
IEEE 488.2 uses two bytes to represent waveform data (14 bit integer). Therefore the number of bytes is always twice the number of data points.

<start>
<binary block>
Start address of the arbitrary waveform
<value> Decimal or integer values

SCPI Status Register
The status registers are used to record and determine the status of the function generator.
The function generator has a number of register groups:
Questionable Status Registers
Standard Event Status Registers
Status Byte Register
As well as the output and error queues.
Each register group is divided into three types of registers: condition registers, event registers and enable registers.
Register types
Condition
Register
The condition registers indicate the state of the function generator in real time. The condition registers are not triggered. I.e., the bits in the condition register change in real time with the instrument status. Reading a condition register will not clear it. The condition registers cannot be cleared or set.
Event Register
The Event Registers indicate if an event has been triggered in the condition registers. The event registers are latched and will remain set unless the
*CLS command is used. Reading an event register will not clear it.
Enable Register
The Enable register determines which status event(s) are enabled. Any status events that are not enabled are ignored. Enabled events are used to summarize the status of that register group.

The Master Summary Status is used with the *STB? query. When the *STB? query is read the MSS bit is not cleared.
The Request Service bit is cleared when it is polled during a serial poll.
Output Queue
Description
The Output queue stores output messages in a
FIFO buffer until read. If the Output Queue has data, the MAV bit in the Status Byte Register is set.
Error Queue
Description
The error queue is queried using the
SYSTem:ERRor? command. The Error queue will set the “Error Queue“ bit in the status byte register if there are any error messages in the error queue.
If the error queue is full the last message will generate a “Queue overflow” error and additional errors will not be stored. If the error queue is empty, “No error” will be returned.
Error messages are stored in the error queue in a first-in-first-out order. The errors messages are character strings that can contain up to 255 characters.
