1 Overview of the 34934A
34934A High Density Matrix Module 12
Practical Examples for Selecting a Matrix Configuration Mode 23
This chapter provides an overview of the 34934A High Density Matrix Module. It
includes operating and general configuration information applicable to all matrix
options from 4x32 to 16x32 and larger, with practical examples of the basic matrix
options.

1 Overview of the 34934A
12 Keysight 34934A User’s Guide
34934A High Density Matrix Module
The 34934A is a 512 crosspoint matrix of non-latching reed switches, which you
can operate in any of six different 1-wire topologies or three different 2-wire
topologies. Larger matrices can be created from the base configurations by linking
34934A modules.
This matrix switch module offers a convenient way for you to connect multiple
instruments to multiple points on your device under test (DUT). Instruments and
DUTs are connected through the rows and columns of the matrix.
Available base matrix configurations:
You may configure a single 34934A module:
–Asquad4x32 matrices (M1H, M1L, M2H, M2L). You can operate these as four
independent matrices or as two independent 2-wire matrices.
–Asdual4x64 matrices (MH, ML). You can operate these as two independent
matrices or as a single 2-wire matrix.
– As a single 4x128 matrix.
–Asdual8x32 matrices (MH, ML). You can operate these as two independent
matrices or as a single 2-wire matrix.
– As a single 8x64 matrix.
– As a single 16x32 matrix.
Chapter 2, “Base Matrix Configuration” provides detailed instructions for
configuring each of these base matrices.
Extended-Row Configurations You can create larger matrix configurations by
combining multiple 34934A modules. For multiple modules with the same base
configuration, extending the rows increases the number of columns in the matrix.
For example, two modules each set to 4x128 would combine to create a 4x256
matrix.
Chapter 3, “Expanded-Row Matrix Configuration” provides detailed instructions
for interconnecting modules to create expanded-row matrices.

Keysight 34934A User’s Guide 13
Operating Considerations
Connection to Voltage Sources
Although flexible, it is possible to connect more than one source at the same time
with the 34934A. Make sure that dangerous or unwanted conditions are not
created by these connections.
Safety Interlock
The 34934A module has a hardware Safety Interlock feature that automatically
opens all 512 of the module’s relays when the associated interlock pins on the
high-density D-Sub connectors (faceplate) or extension headers (terminal block
or configuration block) lose continuity. This prevents signals from your field wiring
from being present on exposed pins on the opposite D-sub connector or extension
header.
If you connect to the D-Subs with custom cabling, you must provide continuity for
the interlock pins as part of your field wiring / DUT assembly. Specific instructions
for providing safety interlock continuity at the D-Sub connectors are provided for
each configuration.
If you connect your field wiring using the optional terminal blocks or configuration
blocks (available from Keysight) you must also provide continuity for the interlock
pins. This can be accomplished by installing the supplied terminators in the
extension headers. Specific instructions for providing safety interlock continuity at
the extension headers are provided for each configuration.
Electrical Considerations
See the Introduction to the Plug In Modules chapter of the 34980A Mainframe
User’s Guide for detailed environmental operating conditions for the 34980A
mainframe and its installed modules. That guidance sets maximum per channel
current and power ratings at rated voltage for pollution degree 2 (possible
condensation) condition, for the 34934A matrix module.
Thermal Considerations
Because of mainframe thermal and power-supply restrictions, you can close no
more than 64 channels (crosspoint relays) on the 34934A at one time. If you try to
close a 65th channel, an error will be generated from the 34980A, and the
channel will remain open.

Connection to the 34980A Analog Buses
This module does not internally connect to the 34980A mainframe’s four 2-wire
(HI, LO) 300V-rated Analog Buses.
– ABUS1 (MEAS) and ABUS2 (SENSE) connect to the internal DMM.
– ABUS3 and ABUS4 are for signal-routing only, and do not connect to the
DMM.
You can connect from a row/column crosspoint directly to the external 9-pin
Analog Bus connector located on the 34980A’s rear panel (see connector pinout
below).
See the “Electrical Operating Conditions” and “Analog Buses” sections of the
34980A Mainframe User’s Guide for complete instructions and safety precautions
for accessing the Analog Buses.

Row Protection
For reed relays, user-attached reactive loads and module parasitic capacitance
may result in high in-rush currents. The 34934A module provides a method of
protecting the reed relays from in-rush current, called Row Protection. The
module incorporates sixteen 100Ω resistors, one for each bank of 32 columns
within a row. Each of these resistors is in parallel with a bypass relay, as shown
below.
The row protection mode is set with the command:
SYSTem:MODe:ROW:PROTection <slot>, <mode>
The mode parameters are listed below along with descriptions of the modes. The
selected mode applies to all channels within all matrices of the 34934A module in
the selected slot.
AUTO100 In this mode, closing any channel also closes the Row Protection
Relay for that row, placing a 100Ωresistor in the signal path from that channel’s
32-column bank (see above). The Row Protection Relay remains closed while any
channel in that 32-channel bank is closed. The protection relay opens after all
channels in that bank are opened.
AUTO0 In this mode, closing a channel also closes the Row Protection Relay for
that row, placing the 100Ωprotection resistor momentarily in the signal path from
that channel’s 32-column bank to dissipate inrush current. The protection relay is
then opened and shunted by the bypass relay.
FIXed In this mode, all 16 Row Protection Relays are closed, placing the 100Ω
resistors in the signal paths from each 32-column bank. This operation is

independent of the state (open, closed) of any channel relays. The Row Protection
Relays remain closed until the row protection mode is changed, the instrument is
reset, or power is cycled to the instrument.
ISOlated In this mode, all 16 Row Protection Relays and Bypass Relays are
open, allowing no signals to pass between 32-column banks via the rows. This
mode only applies to the 4x32, 8x32 and 16x32 matrices. By isolating the rows,
you can route signals column to column within the same bank of 32 columns,
using the row as a connection bus between columns. The Bypass Relays remain
open until the row protection mode is changed, the instrument is reset, or power
is cycled to the instrument. This operation is independent of the state (open,
closed) of any channel relays.
See “Setting the Relay Protection Mode” on page 232 for sample command
examples.
General Configuration Procedures for the 34934A
Base Matrix Configurations
In practice, you will follow these steps to select, configure, and wire a single
34934A matrix module:
1Select a base matrix configuration:
–4x32
–4x64
– 4x128
–8x32
–8x64
– 16x32
The 4x32, 4x64, and 8x32 configurations can be operated as 2-wire channel
pairs programmatically.
NOTE
Fixed mode is not recommended for matrix configurations (i.e. 4x64, 4x128,
8x64) where rows are extended to provided additional columns - unless only DC
signals are used. The extended rows can create large stubs and capacitances.

The silk-screen on each terminal block (34934-001, 34934-002) represents one of
the three configurations supported by each block. Removable silk-screen overlays
are used for each block’s other (two) supported configurations.
The terminal block attaches to the 34934A module’s D-Sub connectors. Matrix
configuration (selection) is accomplished by placing jumpers on the terminal
blocks. You choose a configuration, place jumpers, and then wire your test circuit
to the screw terminals and/or extension headers.

Configuration Blocks
Configuration blocks allow access through pre-made molded cables to the rows
and columns of the matrix. Additionally, the rows can also be wired to 20-pin
expansion headers on the block.
Configuration block 34934C-001 is used with the 4x32, 4x64 and 4x128 matrices.
Configuration block 34934C-002 is used with the 8x32, 8x64 and 16x32 matrices.
The 34934C-001 is shown below.
The configuration block attaches to the 34934A module’s D-Sub connectors.
Matrix configuration (selection) is accomplished by placing jumpers on the
configuration block. You choose a configuration, place jumpers, then wire your
test circuit to the configuration block’s male D-Sub connectors and/or extension
headers. In addition, you will have to short two pins on each D-Sub to provide
safety interlock continuity. All other configuration is done within the block; this
saves significant wiring time compared to direct wiring (which requires
user-supplied configuration jumper wiring between the 34934A’s D-Sub
connectors).
