34980A matrix switch modules

The 34980A matrix modules are full
cross-point matrices that allow you
to connect any row to any column.
This is a convenient way to connect
multiple test instruments to multiple
points on a device under test.

Choose from the following features:

• Latching armature relays—300 V, 1 A

• High-speed reed relays—150 V, 0.5 A

• Configurable dual 4x8 or dual 4x16

modules

• Single-wire configuration (34933A)

• Analog bus expandable rows to

create larger matrices

• Connections via standard 50-pin

Dsub cables or detachable terminal
block

Each cross-point in the matrix switch
has two wires—a high and a low for
the measurement. Or, if you prefer,
the 34933A can be configured as a
single-wire matrix, increasing the
number of channels. The 34933A also
has in-rush resistors on each column
for added protection.

Combine multiple matrix modules
through the 34980A analog buses
to create a larger matrix. Two
matrix rows also can be connected
to the internal DMM for easy
measurements.

Combine your matrix with a multi-
plexer switch to achieve the desired
switching topology and get a lower-
cost solution with better specifications.
All the matrix switches include a
relay counter to help predict when
relays need to be replaced. Use the
sequencing feature to easily change
between different cross-point setups.
