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. | |
| DO NOT connect different types of RF switches to the same channel during | |
