The Agilent 34901A module for the 34970A Data Acquisition/Switch Unit is the most versatile multiplexer for general purpose scanning. It combines dense, multi-function switching with 60 channel/second scan rates to address a broad spectrum of data acquisition applications.

Two- and four-wire channels can be mixed on the same module. Two additional fused inputs (22 channels total) route up to 1A of current to the internal DMM, allowing ac and dc current measurements without the need for external shunt resistors.

The Agilent 34922T is a terminal block for the 34922A 70-channel armature multiplexer. This terminal block is used for discrete wiring. It supports up to 20 AWG wire size typical for <100 connections or 24 AWG for >100 connections. The following two terminal blocks are available to facilitate wiring connections to the 34922A module:

The Agilent 34947A microwave switch for the 34980A Multifunction Switch/Measure Unit offers bi-directional switching for test signals from DC to 26.5 GHz. These switches provide excellent insertion loss, isolation, and VSWR specification. The microwave switches are configured as three independent 1x2 (SPDT) unterminated switches on a single module. For general-purpose microwave switching applications, the module can be used to switch separate signal sources for a multi-band receiver/transmitter testing application.

Designed to meet the needs of a wide range of general-purpose voltage, sensor and transducer logging applications, the PicoLog 1000 Multi-Channel DAQ Series feature independent software-configurable scaling and control outputs, an external terminal board for custom front-end circuitry and a choice of 10 or 12-bit input resolution.

• Up to 16 input channels per data logger
• Up to 4 output channels per data logger
• Use up to 4 data loggers at the same time
• Up to 1 MS/s sample rate
• USB connected and powered
• Data acquisition software and SDK included

The Agilent 34934A module for the 34980A Multifunction Switch/Measure Unit offers the highest density matrix for connecting paths between your device under test and your test equipment, allowing for multiple instrument connections to multiple points on your device under test at the same time. The matrix modules can be expanded with the row expansion kit allowing for up to 4096 cross points in a single mainframe. And with the unique row disconnect feature, you don´t have to worry about the added capacitance when connecting multiple matrix modules. This matrix is easily configured in 1- or 2-wire configurations. The optional configuration block and high density screw terminal block provide ample space for wiring and ensure robust connections to your device under test.

The Agilent N2299A is a 1.5m cable to connect the Device Under Test to any of the N2260A/61A/63A/64A/65A/66A modules.

The Agilent N2294A is a screw terminal block connection accessory for the N2264A 12+3 GP + 16-bit Digital I/O Module.

The Agilent N2292A is a screw terminal block connection accessory for the N2262A 4X8 Matrix Switch Module.

The Agilent 34952A module for the 34980A Multifunction Switch/Measure Unit allows great flexibility for a variety of sense and control applications. It combines four 8-bit channels of digital input and output, a 100 kHz gated totalizer, and two ±12V analog outputs all on a single earth-referenced module. The digital inputs and totalizer input may be included in a scan. Alarm limits for the digital and event counter inputs are evaluated continuously, capturing and logging alarm conditions even between scans.

The digital I/Os support TTL levels. These channels can be used with an external power supply to control external devices or to sense limit switch and digital bus status. There are no complex handshake modes.
