Programmable Attenuators
Frequently Asked Questions about Programmable Attenuators....
What are the applications of Aeroflex / Weinschel
programmable attenuators?
Aeroflex / Weinschel's programmable attenuators are used
to control the power of radio frequency and microwave signals. Applications include control of input power to signal
measuring systems, control of output power from signal
generating systems, adjustment power for BIT error rate
testing, controlling losses in a signal path and simulating the
signal fading of a microwave communication system....to
name just a few.
How do they work?
Aeroflex / Weinschel's programmable attenuators consist of
a series of attenuation pads (cells) that are selectively
inserted into the signal path via a control signal. An example is a series of cells such as 1, 2, 4, 8 and 16 dB arranged
in a binary sequence. Such an attenuator is called a binary
attenuator. Combinations of cells are switched "on" to provide attenuation steps from 0 dB to 31 dB. Another example
is a unit having cell values of 10, 20 and 40 dB which will
provide 10 dB steps between 0 dB and 70 dB.
How are the attenuators switched?
The basic structure of a programmable attenuator is shown
below. There are several ways the attenuator pads are
switched in and out of the RF path. Aeroflex / Weinschel's
3200 series uses TO-5 can relay switches. These are useful up to 2.0 GHz and higher. Aeroflex / Weinschel's 150
series operate up to 26.5 GHz and utilize reed switches
housed within a precision machined cavity.
How fast do the attenuators switch?
Switching speed of mechanically switched attenuators is
typically between 6 and 35 msec. This is the maximum time
between the application of the switching command to the
cell and the cessation of contact bounce. This time is a function of switch structure and size.
What is a latching and
non-latching attenuator?
Non-latching is also called
momentary or fail-safe. For
the non-latching type, the
attenuator is switched to the
attenuation "on" position only
so long as control power is applied to
the switch. As soon as power is
removed the switch reverts to it passive state or fail-safe
state...usually the zero dB state. In latching attenuators
each cell stays in the last setting even if power is removed.
Latching attenuators have two control lines. One control line
causes the attenuator to switch to the "attenuation on" setting while the other control line causes the attenuator to
switch to the zero dB setting. There is normally a permanent
magnet that holds the switch stable in either position.
Each version has its advantages and disadvantages. The
non-latching switch requires constant power to the solenoid
when in the "on" position. On the other hand the latching
version requires greater switch current to overcome it's permanent magnet.
How are the attenuators controlled?
The Model 3200 and 3400 Series non-latching attenuators
require only one 12 volt control line per cell. The direction of
control current is not important.
The Model 150 Series is a latching version using one positive 5 volt or 24 volt common return line and two grounding
control lines.
In order for switching to be guaranteed the voltage between
common and control must be held within specified limits.
Power supply regulation must be kept within range even
while heavy switching current is being drawn. Any cable
voltage drops must be added to the minimum control voltage to obtain the required power supply voltage at the
attenuator.
Aeroflex / Weinschel also manufactures programmable
attenuators using solid state switching that offers faster
switching speeds but their frequency range is more limited
than mechanical step attenuators. Whereas mechanically
switched attenuators operate from DC to their maximum frequency, solid state attenuators have a lower frequency limit.
Solid state attenuators also have lower isolation between
control and through path.
204
Aeroflex / Weinschel's programmable attenuators, such as
the Model 3200T, 3400T and 150T Series feature on-board
TTL drivers. TTL driver boards are also available for most
models.

Programmable Attenuators
What is the switch life of these programmable
attenuators?
Specified life for mechanical switches is normally in the
range of 1 to 10 million switching. This specification is per
switch, independent of the other switches in the attenuator.
For the Model 150 series attenuators the specification is 5
million cycles, i.e. one cycle is the switch moving in both
directions. These specifications are based on the mechanical life of the switch, however, other factors have an impact
on attenuator life. High power operation can have an
adverse effect on the switch contact surfaces. This can
reduce the overall life of the switch by causing the attenuator performance to go outside it's specification.
a single host control interface, suitable for use in larger system and sub-system applications. The built-in driver™
contains non-volatile configuration memory that is used to
hold a wide variety of attenuator and driver-dependent parameters, including serial number, attenuator cell dB values,
relay configurations, and switching requirements, which are
all accessible via the digital interface. This frees the system
designer from such low-level details, allowing faster integration. In either operational mode, the microcontroller
enters an idle condition during periods of inactivity, turning
off all on-board clocks, reducing EMI concerns, and lowering power consumption. On-board regulation for the digital
circuitry allows the programmable attenuator to operate
from a single input supply voltage.
What is monotonicity?
A programmable step attenuator is considered monotonic if
it's attenuation always increases when it is commanded to
increase. This applies on a per frequency basis. For
instance the 20 dB setting at 1 GHz will always be less than
the 21 dB setting at 1 GHz. This does not necessarily mean
that the 20 dB setting at 1 GHz will always be less than the
21 dB setting 18 GHz. Monotonicity is influenced by the
SWR of the individual attenuator cells as the cells are combined to form an attenuation value. It is also influenced by
the summation of individual cell attenuation tolerances as
the cells are combined.

What is the difference between insertion loss and
incremental attenuation?
Programmable attenuators have insertion loss and also
incremental attenuation. Insertion loss is the loss through
the attenuator when all cells are switched to zero dB. It is
the residual loss of the device itself. Insertion loss usually
increases with frequency reaching several dB at the higher
frequencies and generally has very flat frequency response.
Incremental attenuation is the attenuation values of the
attenuators cells relative to the insertion loss. Since insertion loss is always present, the performance of a
programmable attenuator is always given as incremental
attenuation relative to insertion loss. Insertion loss is considered part of the fixed performance of the system path in
which the programmable attenuator is located.
What is the advantages of Attenuators with built-in
driver circuitry?
These attenuators feature an internal microcontroller-based
driver that provides a TTL-level digital interface for control
of the attenuator relays (Figure 1). This card simplifies
operation and interfacing requirements, while at the same
time providing for greatly enhanced flexibility over past
designs. User-selectable modes of operation include both
parallel and serial bus. The parallel mode provides a simple,
one-bit per relay on/off control with internal pullups for use
primarily in single attenuator applications. This mode allows
the attenuator to be controlled via a variety of methods,
such as a TTL-level digital output port, or mechanical toggle switches. The serial mode provides a two-wire serial bus
structure and protocol for connecting a number of devices to

Programmable Attenuators
Intermodulation Distortion in Programmable Attenuators....
W
einschel
has been a major supplier of
programmable attenuators to the RF industry for over
30 years. Historically the most demanding specifications for these components have been low insertion loss and SWR,
combined with a reasonable life expectancy of several million
switching cycles. This was usually adequate for RF instruments
like spectrum analyzers and signal generators, wherein the
attenuator bandwidth rather than the switching speed was of prime
concern. To achieve wide bandwidths the programmable attenuators were mostly of electromechanical design and the linearity of
these passive components was not only assumed but never
questioned by any customer. Intermodulation distortion discussions and problems were usually limited to components such as
amplifiers, mixers and filters.
In recent years, however, wireless communication systems
employing complex digital modulation schemes, increased channel capacity, high transmit power and extremely low receiver
sensitivity have put into question the linearity of passive components. Even very low level multi-tone intermodulation products
generated by attenuators can seriously degrade the efficiency of
a system/ instrument if these products fall within the user passband. For two closely spaced tones at frequencies f1 and f2, the
third order IM products at 2f1 - f2 and 2f2 - f1 , are the most
harmful distortion products. They are harmful because they are
located close to f1 and f2 and virtually impossible to filter out. In
today's base stations the multicarrier power amplifier (MCPA) is
replacing banks of single-channel amplifiers and their corresponding power combining network. MCPAs have the capability
of carrying a number of modulation schemes simultaneously and
can also employ schemes such as dynamic-channel-allocation
(DCA) to use the allocated frequency spectrum more efficiently.
The in-band intermodulation distortion (IMD) performance of
these amplifiers is extremely critical and needs to be measured
using low distortion programmable multi-tone generators whose
IMD performance must be quite superior. This is discussed in the
two case studies cited here.
Electromechanical programmable attenuators obviously
provide a far superior IMD performance than
their corresponding solid state
counterparts employing semiconductor switching elements.
206
However, their slow switch speed, in the order of milliseconds, and short switch life in the order of 5-10 million cycles
make them unattractive in some applications like cell phone testing and other ATE systems. Solid State programmable attenuators
do overcome these two problems and are therefore included here
for IMD performance comparison. It is not the intent of this brief
article to go into the theory of intermodulation distortion. The goal
here is to provide some good basic IMD test data for a
variety of commercial programmable attenuators and let the end
user select the most appropriate type for his application.
Measurement System and Parameters...
All test data presented here was generated using a
commercially available Passive IM Analyzer, Summitek Model
SI-800A which provides a fully integrated system for characterizing distortion produced by cables, attenuators and other passive
devices. Although the system is capable of measuring both,
through and reflected IM3, IM5, IM7 and IM9, the focus here is
only on through IM for the most troublesome third order product,
IM3. To carry out a meaningful comparison between different
attenuators all measurements were carried out using two equal
amplitude input tones at 869 MHz (f1) and 891 MHz(f2) , the IM3
frequency being 847 MHz (2f1-f2). Input carrier power was
stepped in increments of 1 dB from -7dBm to +27dBm. All external adapters and cables were carefully selected to maintain the
system's residual IM level of around -120 dBm. Although the system permitted receiver measurements between -70 to -120 dBm
we restricted all measurements between -85 to -110 dBm by
using a calibrated low IM coupler and attenuators at the output
port of the DUT. One must be aware that the accuracy of such
small signal measurements can easily be off by 2 to 3 dB so
restricting the measurement dynamic range helps reduce the
receiver non-linearity error. Measurements were done over several days to ensure stability and repeatability.
Distortion Comparison for Basic Types of
Programmable Attenuators...
The programmable attenuators discussed here are the
switched type with a discrete number of `cells'. Switching
between the zero and attenuate state on each cell is achieved by
a DPDT switch configuration. The cell values are usually in a
binary sequence. For example a 6 cell/6 bit unit could have 1, 2,
4, 8, 16 and 32 dB sections providing a 63 dB dynamic range in
1dB increments. Four basic families of programmable attenuators are compared, each family being identified by the switch
element used to achieve the transfer from zero to attenuate state.
For the purposes of distortion comparison it was deemed
necessary to select units with similar electrical length and/or
programmability. Both the electromechanical units, TO5 relay
and edge-line type, had an electrical length of about 20 cms. The
two solid state units had 6 cell programmability yielding 63 dB in
1 dB step size. All IM3 vs Pin measurements were done with
the attenuators programmed to be in their characteristic zero
insertion loss state. The zero state was selected because it
generated the highest IM3 levels. The graph below shows the
obvious compromise in IMD performance for the two solid state

types. It is worth noting that the IM3 vs Pin slope is not exactly
3:1 as would be the case in a perfect third order device. The theoretical two tone third order intercept point, IP3, commonly used
as a figure of merit for comparing linearity is shown in the following table at two different input power levels. The input IP3 is
derived from the following relation:
Input IP3 = 3(Pin-α)-IM3 + α
2
where α = zero insertion loss of each unit @ 847 MHz, the IM3 frequency. IM3 and Pin are selected from Table 1.

Programmable Attenuators
Company A offers its IMD series Phase Aligned 8 tone generators to test intermodulation distortion in multi-carrier power
amplifiers. The output level of these generators is accurately controlled using a Weinschel TO5 relay based programmable
attenuator offering over 60 dB dynamic range. Eight +13 dBm
carriers are input to the attenuator. In MCPAs with feedforward
correction, in-band IMD levels could be as low as -75 dBc so
Company A wanted at least -85 dBc at the output of their generator. The first problem was that Weinschel could not simulate the
exact test conditions. This was readily resolved by establishing a
good co-relation between our two tone IM3 measurement and
Company A's 8 tone test. Having employed the best plating techniques and using good low IM connector design the attenuator
was still short of the required IMD spec. The final improvement
was achieved by extensive testing on relays from three different
manufacturers. Figure 2 shows IM3 plots of the two best performers. Manufacturer B consistently provided a 4 to 5 dB
improvement at the two tone level at Pin of +22 dBm and higher.
This corresponded to an acceptable output distortion level for the
Company A generator.
to the customer and suspected to be the prime cause of high IMD
levels. Since the unit was going to be mounted in a benign environment, elimination of the nickel underplate was not thought to
be a problem. Figure 3 demonstrates the tremendous reduction in
IM3 levels upon elimination of the nickel underplate-a significant
40 dB! A further 10-15 dB improvement was achieved by
redesigning the connectors to reduce their passive IMD. The IM
improvement in these connectors would have served no purpose
prior to the elimination of nickel. This is because the main source
of distortion lay behind the connector back plane, along the edge
transmission line, which had a far greater electrical length than
the two connectors.

Case Study 2
Company B manufactures ultra low distortion multi-tone signal generators. Their units offer up to 160 channels from 5 MHz
through 1 GHz. Each carrier can be leveled as high as +10 dBm.
One of their most stringent requirements is a cross modulation
test. The Company B generator specification is -100 dB below the
sideband of a 100% amplitude modulated carrier, which is -110
dBc. The actual components used in the critical path had to
measure -120 dBc or better. Their generator needed an ultra linear attenuator to provide a programmed output level in 0.5 dB
increments. Relay based units were tested and found to be unacceptable. The high performance edge-line attenuators were
expected to solve the problem but at first they too fell short, but
mainly in their zero attenuation state, which generates maximum
distortion. Prior to supplying these units to Company B no customer had asked for a distortion specification on these supposedly
passive attenuators. Environmental performance had warranted
the use of nickel underplate on the edge lines. This was disclosed
208
0
Abundant intermodulation test data for four families of programmable attenuators has been presented in an easy format,
together with their other key performance features. This should
enable instrument and system designers to select the most suitable
type for their application.
The two case studies have also demonstrated that an OEM
component supplier cannot possibly simulate the different distortion test scenarios of every customer. Such tests would be
extremely varied, complex and cost prohibitive. The IM analyzer
used at Weinschel was indeed a narrow band instrument and one
might be concerned about the unit's performance at other frequencies. This is a legitimate concern for the solid state types, in
which the distortion mechanism is a strong function of the operating frequency. For the broadband electromechanical types this is
not a major issue. However, with a meaningful two tone intermodulation measurement it is quite possible to get an excellent
correlation with the customer's test conditions and thereby come
up with a corresponding specification under the two tone test. It
is helpful though, to be able to replicate the total power level that
the unit would be subjected to in the field.

* Use the Cell Configuration table to determine X and Y
for available attenuation ranges.
CONTROL CONFIGURATION:
Standard Unit: One terminal is connected to case ground
and the remaining terminals are provided for activation of
individual cells. Attenuation is fail-safe to "0" setting in the
absence of a control voltage. Application of a voltage (+) to
a particular cell causes it to switch to the attenuate position.
Units with TTL Option: Units with this option are supplied
with a very low profile connectorized TTL interface board
mounted directly to the control terminals. This TTL interface
option is available with either a 10 pin ribbon cable connector or a 15 pin "D" connector (limited models), refer to list
below. Each type is supplied with a mating connector. Refer
to Physical Dimensions for mating connector pin/wiring
details. Two wires are specified for supply voltage and
ground. The remaining wires will accept TTL control signals
to activate or de-activate a particular attenuation cell. A TTL
high will energize a cell to the high attenuation state,
whereas a TTL low will maintain a cell in its zero attenuation
state.
To order 3200 Series Attenuators with this option add -1 to
basic model number for ribbon cable connector and -2 for
the "D" connector. Example: Model 3201-1E with a TTL
interface board would be 3201-1E-1. Mating connector is
provided. To order a TTL Driver board separately for an

ACCESSORIES
Programmable Attenuator/Switch Controller: The Model
8210A Programmable Attenuator/Switch Controller provides
a flexible, low cost solution for the operation of programmable step attenuators and other electromechanical devices
under computer control. Designed to interface to Aeroflex /
Weinschel's intelligent programmable attenuators, the
8210A represents a new concept in device control
applications for bench test and subsystem designs. The
8210A provides a high-level interface from various industry
standard communications interfaces, including IEEE-488
and RS232/RS422/RS485, to the programmable
attenuator’s serial Driver Interface Bus.
CONTROL CONFIGURATION
These programmable attenuators feature an internal microcontroller-based driver that provides a TTL-level digital
interface for control of the attenuator relays. This card simplifies operation and interfacing requirements, while at the
same time providing for greatly enhanced flexibility over
past designs. User-selectable modes of operation include
both parallel and serial bus. The parallel mode provides a
simple, one-bit per relay on/off control with internal pullups
for use primarily in single attenuator applications. This mode
allows the attenuator to be controlled via a variety of methods, such as a TTL-level digital output port, or mechanical
toggle switches. The device bus provides a two-wire serial
bus structure and protocol for connecting a number of
devices to a single host control interface, suitable for use in
larger system and sub-system applications. The digital
interface contains non-volatile configuration memory that is
used to hold a wide variety of attenuator and driver-dependent parameters, including serial number, attenuator cell dB
values, relay configurations, and switching requirements,
which are all accessible via the digital interface.
In either operational mode, the microcontroller enters an
idle condition during periods of inactivity, turning off all
on-board clocks, reducing EMI concerns, and lowering
power consumption. On-board regulation for the digital
circuitry allows the attenuator to operate from a single input
supply voltage.

to Model 3406T and 3408T data sheet for more information.
Units with TTL Option: Units with this options are supplied
with a very low profile connectorized TTL interface board
mounted directly to the control terminals. This TTL interface
option is available with a 10 pin ribbon cable connector and
is supplied with a mating connector. Refer to Physical
Dimensions for mating connector pin/wiring details. Two
wires are specified for supply voltage and ground. The
remaining wires will accept TTL control signals to activate or
de-activate a particular attenuation cell. A TTL high will
energize a cell to the high attenuation state, whereas a TTL
low will maintain a cell in its zero attenuation state.
To order 3400 Series Attenuators with this option add -1 to
basic model number for ribbon cable connector. Example:
Model 3406-63 with a TTL interface would be 3406-63-1.
Note: Control is non-latching and requires a continuous
control signal for the period of time in which attenuation is
required.

Description
This line of intelligent programmable step attenuators with a
built-in digital interface are designed to simplify the control
and integration of these devices into subsystem and bench
applications. This series of Programmable Step Attenuators
is designed for use in automatic test equipment and OEM
systems operating in the dc to 6 GHz frequency range.
These models are available in many standard attenuation
ranges and cell configurations. Each cell contains a doublepole, double-throw relay that provides a minimum loss or
attenuated path for the RF signal.
Microstrip circuitry and special compensation techniques
produce flat attenuation versus frequency characteristics.
The microstrip construction, using thick-film circuit
elements, ensures product uniformity. To minimize RF leakage, the 3400T Series Attenuators are provided with
gold-plated contact areas and feedthrough filters at each
control terminal.

Relay Switched Programmable Attenuators

PROGRAMMABILITY: In each programmable step
Attenuator, solenoids are used to switch the internal resistor
card of each cell into and out of the circuit. Once the cell is
switched, the solenoid is magnetically latched into position
and is able to withstand extreme shock and vibration.
Internal circuitry is included to interrupt the coil current after
switching is complete. This reduces power dissipation even
if power is continuously applied. The switching time for each
cell is rated at 20 msec maximum which includes the contact settling time.
Description
The Model 150, 151 and 152 Programmable Step
Attenuators represent the widest variety of programmable
attenuators available. This attenuator design is the result of
an extensive development program and offers long reliable
operation with exceptional accuracy and repeatability.
These attenuators can provide programmable adjustments
of RF signal levels in precise steps of 1 dB, 5 dB, 10 dB, or
with custom steps available. Each attenuator consists of a
cascaded assembly of
switched attenuator cells
(Figure 1). The attenuator
elements located in the
attenuator cell are created
by a thin-film process
which provides exceptional long-term stability,
low power and temperature coefficients. This
series uses a reed switching structure that provides
rapid switching together
with low insertion loss.

BROADBAND ACCURACY & LOW SWR: The use of
Aeroflex / Weinschel's proprietary thin-film resistor process
provides these programmable step attenuators with a high
degree of accuracy and the lowest possible SWR uncertainty (refer to specifications for actual values). This thin film
process permits the construction of circuits which are truly
distributed and without stray reactances, even at the higher
microwave frequencies.
RELIABILITY:
Each programmable step attenuator is
composed of 3 to 5 (4 in most models) cells. As with all
mechanical designs, usable life becomes a primary concern
to the user. With this in mind Aeroflex / Weinschel backs all
these attenuators with a rated switch life of 5 million
operations per cell. Standardized testing is also performed
on each programmable step attenuator over its operating
frequency range by a computer controlled Aeroflex /
Weinschel Attenuation Measurement System which is
traceable to NIST standards.
ENVIRONMENTAL: These Model 150 Programmable Step
Attenuators have undergone an extensive environmental
qualification program and have been subjected to
temperature, shock, vibration, and humidity conditions per
MIL-STD-202F. These programmable step attenuators
operate within these specifications at an ambient
temperature of -20° to +75°C. Operating beyond these
limits will adversely affect the accuracy and could damage
the internal circuitry.

RoHS
The attenuator elements located in the attenuator cell are
created by a thin-film process which provides exceptional
long-term stability, low power and temperature coefficients.
This series of step attenuators uses a reed switching structure that provides rapid switching together with low insertion
loss.
Description
Aeroflex / Weinschel’s line of intelligent programmable step
attenuators with a built-in TTL interface (Figure 1). These
models are designed to simplify the control and integration
of these devices into subsystem and bench applications.
These intelligent attenuators offer the same long reliable
operation with exceptional accuracy and repeatability as
with our other 150 Series Programmable Attenuators. They
provide programmable adjustments of RF signal levels in
precise steps of 1 dB, 5 dB, 10 dB, or with custom steps
available. Each attenuator consists of a cascaded assembly
of switched attenuator cells and a internal TTL interface.

BUILT-IN DRIVER CIRCUITRY:
These programmable
attenuators feature an internal microcontroller-based driver
that provides a TTL-level digital interface for control of the
attenuator relays. This card simplifies operation and interfacing requirements, while at the same time providing for
greatly enhanced flexibility over past designs. User selectable modes of operation include both parallel and serial
bus. The parallel mode provides a simple, one-bit per relay
on/off control with internal pullups for use primarily in single
attenuator applications. This mode allows the attenuator to
be controlled via a variety of methods, such as a TTL-level
digital output port, or mechanical toggle switches. The
device bus provides a two-wire serial bus structure and
protocol for connecting a number of devices to a single host
control interface, suitable for use in larger system and
sub-system applications. The driver interface contains
non-volatile configuration memory that is used to hold a
wide variety of attenuator and driver-dependent parameters, including serial number, attenuator cell dB values,
relay configurations, and switching requirements, which are
all accessible via the digital interface. This frees the system
designer from such low-level details, allowing faster integration. In either operational mode, the microcontroller
enters an idle condition during periods of inactivity, turning
off all on-board clocks, reducing EMI concerns, and lowering power consumption. On-board regulation for the digital
circuitry allows the programmable attenuator to operate
from a single input supply voltage.

Relay Switched Programmable Attenuators

PROGRAMMABILITY: In each programmable step
Attenuator, solenoids are used to switch the internal resistor
card of each cell into and out of the circuit. Once the cell is
switched, the solenoid is magnetically latched into position
and is able to withstand extreme shock and vibration.
Internal circuitry is included to interrupt the coil current after
switching is complete. This reduces power dissipation even
if power is continuously applied. The switching time for each
cell is rated at 20 msec maximum which includes the contact settling time.
Description
The Model 150, 151 and 152 Programmable Step
Attenuators represent the widest variety of programmable
attenuators available. This attenuator design is the result of
an extensive development program and offers long reliable
operation with exceptional accuracy and repeatability.
These attenuators can provide programmable adjustments
of RF signal levels in precise steps of 1 dB, 5 dB, 10 dB, or
with custom steps available. Each attenuator consists of a
cascaded assembly of
switched attenuator cells
(Figure 1). The attenuator
elements located in the
attenuator cell are created
by a thin-film process
which provides exceptional long-term stability,
low power and temperature coefficients. This
series uses a reed switching structure that provides
rapid switching together
with low insertion loss.
Other features include:

BROADBAND ACCURACY & LOW SWR: The use of
Aeroflex / Weinschel's proprietary thin-film resistor process
provides these programmable step attenuators with a high
degree of accuracy and the lowest possible SWR uncertainty (refer to specifications for actual values). This thin film
process permits the construction of circuits which are truly
distributed and without stray reactances, even at the higher
microwave frequencies.
RELIABILITY:
Each programmable step attenuator is
composed of 3 to 5 (4 in most models) cells. As with all
mechanical designs, usable life becomes a primary concern
to the user. With this in mind Aeroflex / Weinschel backs all
these attenuators with a rated switch life of 5 million
operations per cell. Standardized testing is also performed
on each programmable step attenuator over its operating
frequency range by a computer controlled Aeroflex /
Weinschel Attenuation Measurement System which is
traceable to NIST standards.
ENVIRONMENTAL: These Model 150 Programmable Step
Attenuators have undergone an extensive environmental
qualification program and have been subjected to
temperature, shock, vibration, and humidity conditions per
MIL-STD-202F. These programmable step attenuators
operate within these specifications at an ambient
temperature of -20° to +75°C. Operating beyond these
limits will adversely affect the accuracy and could damage
the internal circuitry.

Description
This series of Programmable Step Attenuators provide attenuation from 0-70 dB or 0–110 dB in 10 dB
steps. These attenuators provide programmable
adjustments of RF signal levels in precise steps of 10
dB and consist of a cascaded assembly of switched
attenuator cells (Figure 1). The attenuator elements
located in the attenuator cell are created by a thin-film
process which provides exceptional long-term stability, low power and temperature coefficients. This
series uses a reed switching structure that provides
rapid switching together with low insertion loss. The
153 series in available in three cell (153-70) and four
cell (153-110) configurations.

Internal
Switching
Circuit
PROGRAMMABILITY: In each programmable step
attenuator, solenoid are used to switch the internal
resistor card of each cell into and out of the circuit.
With positive voltage applied to the common pin (#6)
the state (attenuator card or thru line) of a particular
section is determined by connecting it’s attenuator
card or thru pin to ground. Once the cell is switched,
the solenoid is magnetically latched into position and
is able to withstand extreme shock and vibration.
Internal circuitry is included to interrupt the coil current
after switching is complete. This reduces power dissipation even if power is continuously applied. The
switching time for each cell is rated at 20 msec maximum which includes the contact settling time.
Also integrated in the design is solid state dc switching circuitry that avoids the relatively high failure rate
of mechanical DC switches. Each attenuator section
is controlled by its own driver circuit, which requires
+24V nominal, 125 mA.

low will maintain a cell in its zero attenuation state.
USING USB CONFIGURATION: The USB interface is
compatible with standard USB 2.0 interfaces. In USB mode,
DC power to the attenuator is provided by the host USB
connection. The attenuator operates as a USB CDC device
and accepts simple ASCII text commands. This allows the
unit to be controlled from any system capable of sending
data via a standard COM port-style interface.
USING TTL CONTROL: Each unit is supplied with a
mating 10 pin connector (Amp 746285-1). Refer to Physical
Dimensions for mating connector pin/wiring details. Two
pins are specified for supply voltage and ground. The
remaining pins will accept TTL control signals to activate or
de-activate a particular attenuation cell. A TTL high will

Programmable Attenuators
Models 8310 & 8311
Programmable Attenuator Units
IEEE-488
RS232\RS422/RS485
Now Available with Ethernet Control!
Description
Aeroflex / Weinschel’s 8310 and 8311Series Programmable
Attenuator Units represent a new concept in programmable
attenuation for bench test and subsystem applications.
Standard 8310 Series designs house and control various
Aeroflex / Weinschel Programmable Attenuator Models
(3200T, 150T, and 4200 Series) via front panel controls or
standard communications interfaces including GPIB (IEEE488), Ethernet and RS-232/RS-422/RS485. This series
combines the features of the Aeroflex / Weinschel 8210A
Device Controller with a front panel user interface to form a
flexible, easy to use solution.
Features
o Provides a flexible, easy to program, low cost solution
for your bench test/calibration setups and subsystem
applications.
o Multi-Channel attenuation paths (up to 4 input/outputs
for 8310 & up to 6 input/outputs for 8311)
o Relative vs. Nominal attenuation step function.
o Wide choice of Frequency & Attenuation Ranges.
- dc to 1, 2, 3, 6 & 18 GHz
- NEW dc to 6 GHz Models
- up to 127 dB
- Solid-State (GaAs FET *& PIN)
- Relay Switched
o Models with Ethernet Option - Specify when ordering.
o Accuracy & Repeatability.
o Designed to interface with Aeroflex / Weinschel’s line
of digitally controlled programmable attenuators and
other electromechanical devices.
o Designed to interface with industry standard
communication interfaces:
- GPIB/IEEE-488 (HS-488 ready)
- RS-232, RS-422, RS-485
- New Models with Ethernet Control (10 BaseT)
o Rack Configurable: Model 8310 Series can be rack
mounted either as a single unit using Rack Mounting Kit
(P/N 193-8033-1) or two Model 8310's can be mounted
together using Rack Mounting Kit (P/N 193-8033-2).
These kits fit into any rack or cabinet that is designed
per EIA RS-310 or MIL-STD-189. Rack ears are supplied with Model 8311 Series units.
Most 8310 Series are single channel configurations where
RF signal is routed through either the front or rear mounted
Ports A & B but can be configured for up to four channels of
attenuation, RF switching, amplification or other functions.
Multiple programmable attenuators can be used inconjuction with other coaxial devices such as switches, power
combiners, directional couplers, and filters creating single or
multichannel subsystems.
Multi-Channel 19” Rack Size Versions
Applications
Applications for the 8310 and 8311 Series range from
providing control of a single Programmable Attenuator in a
bench test/lab environment using a PC and a terminal emulator, to complex system applications where the 8310/8311
Series are employed to control many devices to create custom/ semi-custom subsystems to reduce overall design
cost. Aeroflex / Weinschel can provide a variety of custom
designed driver interfaces for various devices, such as RF
switches, relays, pin attenuators, motorized step attenuators, displays, and other devices, as well as complete
subsystem design and integration services. Contact us with
your specialized needs.

ethernet, USB and Serial communications interfaces. A
GPIB (IEEE-488) interface is also available as an option.
The 8320 series are single or dual channel configurations
housed in half rack enclosures. The 8321 series are multichannel configurations housed in 19 inch enclosures and
can be configured for up to 12 attenuation channels. Both
series can be configured for front or rear and through (front
to rear) is only available for 8321 Series.
Aeroflex / Weinschel also provides custom subsystems
where a variety of test configurations can be incorporated
within a single unit. Contact us with your specialized needs.
o Rack Configurable: Rack ears are supplied with Model
8321 Series units only.
Applications
Applications for the 8320 and 8321 Series range from
providing control of a single Programmable Attenuator in a
bench test/lab environment, to complex system applications
where the 8320/8321 Series are employed inconjuction with
many devices to create custom subsystems to reduce overall design cost. Multiple programmable attenuators can be
used in conjuction with other coaxial devices such as
switches, power combiners, directional couplers, and filters
to create various multi-channel test configurations.

High Power Programmable Attenuator
IEEE-488
RS232\RS422
100 Watt Hot Switching Capability
Features
o Available in 0-15 dB or 0-31 dB Configurations.
o Provides a flexible, easy to program, low cost solution
for your bench test/calibration setups and subsystem
applications.
o Relative vs. Nominal attenuation step function.
o DC to 13.0 GHz Operation.
o High Accuracy & Repeatability.

Description
Aeroflex / Weinschel's design approach uses a highly
adaptable platform that allows configuration of the step
attenuator to the customers requirements. When the controller requests a new attenuation level the input switch
terminates the input signal into a 50 Ohm load. (See Figure
1) This input switch is hot switchable at 100 Watts of input
power. This will remove the high power signal from the main
signal path. With no signal connected to the attenuator path
the controller then commands the series of relays to configure the attenuator for the requested attenuation value. Then
the input switch re-connects the input signal to the attenuator path. The system can be operated with either a remote
controller (IEEE-488 or RS-232) or through front panel
control.
- GPIB/IEEE-488 (HS-488 ready)
- RS-232, RS-422
o Built-in monitoring for switching input power into the
load in case of fan failure.
o Rack Configurable: A Rack Mounting Kit is included
for easily mounting the Model 8312 into any rack or
cabinet that is designed per EIA RS-310 or
MIL-STD-189.

Description
Model 8210A represents a new concept in device control
applications and provides a high level interface from various
industry standard communications interfaces to the serial
Driver Interface Bus.
The Device Interface Bus (DIB) is a system for connecting
a number of relatively low-speed I/O devices to a host, providing a simple, uniform and inexpensive way to control a
variety of devices via a single port. The DIB is based on the
two-wire serial bus and several software protocol layers that
allow the Model 8210A to address up to 125 peripheral
devices with serial data rates of up to 100 KHz. The DIB
may also be used to supply DC power to the devices, resulting in a simple, low-cost interconnection system.
This Programmable attenuator/switch controller is available
in two models, each providing a different type of communications interface to suit user configuration requirements.
Each model contains similar capabilities, and provides
switch-selectable parameters to the interfaces’ operation.
Typical Capacity: Control a subsystem consisting of 32
individual 8-cell programmable attenuators plus 16
DPDT switches.

Notes:
1. GPIB/IEEE-488 model allows user-selectable addresses.
2. RS-232 can be used with standard PC serial port for short and medium distances (up to approximately 50 ft).
3. RS-422, designed for very long distance communications (4000 ft) & optimized as a single node protocol, typically with one device connected to a
single port.
4. RS-485, designed for very long distance communications (4000 ft) & optimized for multi-drop connections that can used to create a low cost network.
