7153
4×5 Low Current Matrix Card
High Voltage
The Model 7153 is designed to switch low level,
high voltage, and high impedance signals for
applications such as parametric tests on semi-
conductor devices . The 7153 allows signal levels
up to 1300V while maintaining offset current of
<1pA (typically 10fA) and path isolation >10
13
W .
Each crosspoint is a 2-pole relay to switch both
signal and guard . Interconnect between the
matrix and instruments such as the Model 237
SMU is done with the 7153-TRX cable . This cable
has an M-series connector for the matrix and five
3-slot male triax connectors at the opposite end .
The cable will mate with the row or column con-
nectors of the Model 7153 .

Guard) .

10-channel
The Model 7154 switches voltages to 1100V peak
or currents to 0 .5A . The current carry capacity of
each relay contact is 1A . Two-pole relays switch
both circuit High and Low for full floating mea-
surements and each input line is fuse protected
against current overload . A Guard input common
to all channels is provided for shielding or as a
Guard driven from a single instrument . Guards
may be isolated by removing jumpers installed at
each input . Multiple switched guard circuits can
be achieved by removing the jumper and con-
necting circuit Guard to the Low input terminal .
CHANNELS PER CARD:
10 .
CONTACT CONFIGURATION:
2-pole Form A with user-
selectable shield or driven Guard . Each pole is fused using
#38AWG magnet wire .
CONNECTOR TyPE:
Screw terminals, #16AWG maximum
wire size .
RELAy DRIVE CURRENT:
57mA per relay typical .
MAXIMUM SIGNAL LEVEL:
1100V peak, 0 .5A DC or rms
switched, 1A DC or rms carry, 10W .
