Agilent / Keysight 87130A Attenuator/Switch Driver

The Agilent/Keysight 87130A Attenuator/Switch Driver is a GPIB-compatible instrument designed to control and drive electromechanical switches and step attenuators. It serves as a versatile component within RF and microwave automated test equipment (ATE) systems, enabling remote automation of signal path selection and the creation of repeatable test environments. This unit is part of Keysight’s System II family and is a 3.5-inch, full-width device.

### Technical Specifications

* **Control Capability:**
* The standard instrument is equipped with a single internal driver board capable of driving up to 31 switch and/or attenuator sections.
* The drive capability can be expanded by externally connecting up to seven additional HP 84940A driver boards.
* With external driver boards, the Agilent/Keysight 87130A can control and sense switching for up to 248 switches or attenuator sections.
* It can concurrently drive up to two Keysight 8494/5/6/7 programmable attenuators and two electromechanical switches (e.g., Keysight 8761, 8762, or 8765 Series).
* **Sensing Capability (Readback):**
* The 87130A features sensing capability, often referred to as “readback.”
* This allows the driver to monitor the position or state of connected switches or attenuator sections by sensing the voltage on their drive lines.
* This feature aids in verifying that a switch or attenuator section is in the intended state.
* **Internal Power Supply:**
* The 87130A includes an internal 24 VDC power supply for driving switches and attenuators.

### Interfaces

* **Primary Interface:**
* GPIB (HP-IB) compatible.
* This enables remote control and automation of test sequences.

### Physical Characteristics

* **Form Factor:**
* 3.5-inch, full-width instrument.
