Description
API Weinschel’s new 4209-18-63 Solid-State Programmable Attenuators operate
over the 0.1 to 18 GHz frequency range and are available in an attenuation range
of 0 to 63 dB in 0.5 dB steps. These units can be controlled using parallel (TTL
compatible), I2C, SPI, UART, or USB interfaces.

Control Configuration
Units are supplied with both an AUX connector for operation in either a parallel
(TTL compatible) mode or I2C, SPI, UART modes and a USB connector (Mini-B)
for USB 2.0 operation. The main mode of operation is determined internally by
the source of DC power to the unit.
USING AUX CONTROL:
Each unit is supplied with a mating 10 pin connector
(Amp 746285-1). Refer to the table in page 5 for mating connector pin/wiring
details. There are four user-selectable digital interface AUX modes: PIO, I2C,
SPI, and UART. In addition there are three AUX application modes (PIOSW,
PULSE, and FADE) that allow the generation of RF patterns when operating
standalone. The AUX mode selection is done via USB command (see SET AUX)
and is stored in non-volatile memory (NVM) so that changes to the mode will be
automatically applied at startup. Additional information is presented in the
Operating & Installation Manual, IM-672.
USING USB CONFIGURATION:
In USB mode the attenuator is controlled and
powered via a standard USB 2.0 connection to a USB host. The 4209 series
operates as a USB CDC device (USB VID=25EA, PID=106D), so it may be
controlled via any software that can communicate to a standard virtual COM port.
Programming is done via simple ASCII text-based message strings to control the
device.

Control Software Included
API Weinschel’s LabView based USB Control Center Software
(AUCS) can also be used in the operation of this series of digital
attenuators. The AUCS will allow the user to setup, control, and
perform test and measurements over a standard USB 2.0
communication interface. Additional information is available in
the Operating & Installation Manual, IM-611.

X% is the percentage of the nominal attenuation setting. For example the accuracy of 30 dB @ 18 GHz is ± (0.4+0.02x30) dB. This
equates to ±1.0 dB which means when setting the attenuator at 30 dB, the actual measured normalized value could be between 29 dB
and 31 dB.
Measured with two tones at +14 dBm, 1 MHz spacing.
The values in the table apply at room temperature unless otherwise specified.
DC blocking is required when the RF input or output DC line potential is not 0 V.
