2.5 Computer Operation
The EM-2115 Interference Analyzer is operated remotely using a computer supplying
control information through the IEEE Std 488-1978 General Purpose Interface Bus (GPIB).
The current firmware version level being used by the EM-2115 will be displayed on the
front panel Frequency Display if the Local pushbutton Switch is pushed when the receiver is in
local mode.
Section 2.5.1 provides a typical equipment setup for operation using the GPIB interface.
The commands listed in Section 2.5 are all EM-2115 device dependent commands issued
as ASCII commands over the GPIB. EM-2115 Device Dependent Commands are listed in Sec-
tion 2.5.5. In each case listed, the EM-2115 is a listener as defined in the IEEE Std 488-1978.
Some of the functions controlled through the Bus are:
a. Bus Address j. Dump Command Logic
b. AFC k. FM Logic
c. AM Logic l. Frequency Tuning
d. Attenuator Logic m. DVM Read
e. Band Logic n. Frequency Read
f. Bandwidth Logic o. Go To Local
g. BFO Logic p. Local Lockout Logic
h. Cal Command q. Switching Unit Control
I. Detector Logic
2.5.1 Equipment Setup
NOTE: The following setup assumes a test system consisting of an
EM-2115 Interference Analyzer plus computer.
To operate the EM-2115 remotely:
a. Connect the GPIB Cable (24 pin) to the EM-2115 rear panel IEEE STD 488 Port
Connector.
b. Verify that no other device is assigned the Bus Address for the EM-2115. If as-
signed to another device, use the procedure in 2.5.2 to select a new bus address for
the unit. The new bus address is implemented immediately upon being entered.
