34939A 64-Channel Form A General Purpose Switch for 34980A
The Keysight 34939A is a high density general-purpose switch module for the 34980A Multifunction Switch/Measure Unit. It has 64 independent single-pole, single-throw (SPST) relays that can switch 1A and carry 2A. This module can be used to cycle power to products under test, control indicator and status lights, and to actuate external power relays and solenoids. The relays are 100V, 1A contacts and can handle up to 60W. Standard 78-pin Dsub connectors allow for use with standard cables, screw terminal blocks, or mass interconnect solutions.

The Keysight N3306A is a 600 W (0-120A, 0-60V) electronic load module for use in either the N3300A or N3301A electronic load mainframe in system applications. The N3306A load module is fast and accurate, for programming in constant current, constant voltage, or constant resistance modes, or for making voltage, current or power measurements. The N3306A can also digitize waveforms.
Testing multiple output dc power supplies and dc-dc converters can be very time consuming if each output must be tested sequentially. If measurements are being made through a MUX using one DMM, this is what will happen. Using the built-in measurement capabilities of the N3300A electronic loads, all outputs can be measured simultaneously. Alternatively, multiple single output power sources can be tested simultaneously.
A single GPIB address is all you need for complete control and read-back of the N3306A load module within a single N3300A or N3301A mainframe. The N3306A electronic load provides fast operation and the accurate programming and read-back needed for high-volume DC power supply test systems.
