1-4 Agilent 87130A Operating and Service Manual
Introducing the 87130A Attenuator/Switch Driver
Features of the Attenuator/Switch Driver
Compatible Switches
and Attenuators
The attenuator/ switch driver is designed to drive Agilent switches and
attenuators shown in the tables below.
NOTE If you are using switches or attenuators made by another company, check
their switching characteristic against those specified in Chapter 3,
“Specifications”.
All Agilent switches and attenuators have internal clamp diodes to limit
reverse EMF energy from the switch solenoid. If other switches are used,
this energy must be limited to less than 10 millijoules to prevent damage to
the switch driver circuit.
