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

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 M937xA Series or the 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

1. Serial signals from 8-bit I/O can provide up to 4-channels RFFE-like interface with software selectable

clock rate (25 MHz maximum). Please refer to the help file for detail.
