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 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.
