M9341A PXIe Digital I/O M9341B PXIe Digital/Analog I/O

M9341A

Overview

The Keysight M9341A Digital I/O with the 24-bit digital I/O connector and triggering ports provides communication signals between the PXI vector network analyzer (VNA) installed in the same PXI chassis and an external handler. This allows the PXI VNA such as the Keysight M980xA Series, M937xA, or M9485A to be used in an automated test environment, where devices to be tested are inserted into a test fixture by a part handler, and sorted into pass/fail bins by the handler after testing is complete. By connecting the part handler to the M9341A digital I/O connector, the VNA and part handler can synchronize their activities in a way that makes automated testing possible. The M9341A digital I/O also compatible with the 24-bit digital I/O connector on the rear panel of the Keysight PNA and ENA Series.

Key specifications/features

  • Digital I/O for communication for the PXI VNA with external peripherals (i.e. handler)
  • Synchronized measurements with the PXI VNA in an automated test environment
  • Compatible with the 24-bit digital I/O connector on the PNA and ENA

M9341B

Overview

The Keysight M9341B PXIe Digital and Analog I/O is equipped with a 24-bit digital I/O and an 8-bit digital I/O to allow users to control the device under test (DUT) directly with serial or parallel digital signals1. For example, the signals from the M9341B can be applied to select operation modes of the RF front-end module which integrates power amplifiers, switches, low noise amplifiers, duplexer or filters in a single component. The operation with the M9341B is synchronized with the measurement sweep by the Keysight PXI VNA such as the M980xA Series, M937xA, or M9485A, greatly improving measurement throughput. For more comprehensive analysis, the M9341B has four analog input connectors to allow sensing of DC voltages from the DUT. The measured DC voltage can be displayed on the PXI VNA screen. The 1-slot module also supports two variable DC source outputs to control the DUT, while the DC source current can be monitored during measurements.

Key specifications/features

  • 8-bit digital I/O for controlling DUT operation mode with serial/parallel signals
  • 24-bit digital I/O for communication for the PXI VNA with external peripherals (i.e. handler)
  • Synchronized DC measurements with the PXI VNA. Two DC source outputs (up to ±10 V) with current monitor functions and four DC source inputs for sensing DC voltages from the DUT

Specifications

Definitions

Specification (spec.):

Warranted performance. All specifications apply at 25 ºC (± 5 ºC) range ambient and module temperature between 27 ºC to 39 ºC as reported by the module, unless other[1]wise stated, and 45 minutes after the module has been turned on.1 Specifications include guard bands to account for the expected statistical performance distribution, measure[1]ment uncertainties, and changes in performance due to environmental conditions.

Typical (typ.):

Expected performance of an average unit which does not include guardbands.

General Characteristics:

A general, descriptive term that does not imply a level of performance.

Boundary Conditions:

If the same boundary conditions fall under more than one category in a table, apply the

best value.
