Introduction
The Agilent U2121A- 101 (also known as U2931A) RF switch driver
with cable is an adapter board designed for use with the Agilent
U2121A digital IO device. It enables you to control various types of
RF switches easily and has enhanced driving capability and consists
of different types of connectors to suit different switches.
The U2121A- 101 purchase consists of a driver interface module, an
interface cable (equipped with a 37- pin D- sub connector on one end
and four 10- way terminal block connectors on the other end), a
10- pin to D- sub adapter, and a 24 VDC, 2.5 A power adapter. This
module is connected to the U2121A using the provided interface
cable. You can also use the Y1157A[1] cable, which is a 10- pin ribbon
connector to 9- pin D- Sub cable kit for the Agilent N1810/11/12
coaxial switches.
This module is consists of five RF switch driver channels and one
general IO terminal. Each channel is pre- programmed to drive three
different types of Agilent RF switches. Only one type of RF switch
can be connected to a single channel during operation.
The U2121A-101 module is designed to handle 24 VDC switches.
[1] Refer to Appendix B for Y1157A cable kit assembly.
CAUTION
DO NOT connect different types of RF switches to the same channel during
operating time.

Power supply
The switches on this module are powered by the provided power
adapter. There is only one power supply voltage available for this
module, which is 24 VDC, 2.5 A.
Power consumption
The U2121A- 101 can drive up to 1500 mA continuously using the
provided power supply. For each channel, it is able to drive up to 300
mA load per switch. Precaution must be taken to ensure that the
total current consumption on all channels is not more than 1500 mA,
which is the maximum driving capability of the module.
