CELL CONFIGURATIONS:
Description
The 3200 Series Programmable Step Attenuators are
designed for use in automatic test equipment and OEM
systems operating in the dc to 3 GHz frequency range. This
series is available in many standard attenuation ranges and
cell configurations. Custom designed configurations are
available upon request. Each cell contains a standard TO-5
type double-pole, double-throw relay that provides a
zero path 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 ele-
ments, ensures product uniformity. To minimize RF
leakage, the 3200 Series Attenuators are provided with
gold-plated contact areas and feedthrough filters at each
control terminal.

3209-1, 3209-1E: 159 g (5.6 oz)
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 connec-
tor 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 3201-1 with a TTL inter-
face board would be 3201-1-1. Mating connector is
provided. To order a TTL Driver board separately for an
existing 3200 Series Attenuator, use the following:
