HP 8642A Operation And Calibration Manual

Model 8642A/B
Installation
HP-IB Address Selection ~
The Signal Generator's address is set to 19 a t the factory both in RAM memory and an internal
switch located inside the instrument. The address stored in RAM remains valid through switch-
ing the power from standby to on and unplugging of the ac power cord (unless the internal bat-
tery power is lost which would cause RAM memory to be lost). If RAM memory is ever lost, the
address on the internal switch is read and becomes the address at turn on. Refer to page 3-8 for
procedures to set the Signal Generator's HP- IB address.
Interconnections ~
Interconnection da ta for the Hewlett-Packard Interface Bus is provided in Figure 2 - 2, Hewlett-
Packard Interface Bus Connections.
