Chapter 5, Advanced Operations
Instrument Initialization
The Front-panel Reset condition in the Test Set was specifically designed to
configure the instruments for manual testing of an FM radio. The Front-panel
Reset default display screen is the RX TEST screen. Other operational
characteristics are also affected by the Front-panel Reset as follows:
• All pending operations are aborted.
• Measurement triggering is set to TRIG:MODE:SETT FULL;RETR REP.
• Any previously received Operation Complete command (*OPC) is cleared.
• Any previously received Operation Complete query command (*OPC?) is cleared.
• The Test Set’s display screen is in the UNLOCKED state.
• The Power-up self-test diagnostics are not performed.
• The GPIB interface is not reset (any pending Service Request is not cleared.)
• The Contents of the SAVE/RECALL registers are not affected.
• Calibration data is not affected.
• All Enable registers are unaffected: Service Request, Standard Event, Communicate,
Hardware #1, Hardware #2, Operation, Calibration, Call Processing and Questionable
Data/Signal.
• All Negative Transition Filter registers are unaffected: Communicate, Hardware #1,
Hardware #2, Operation, Calibration,Call Processing and Questionable Data/Signal.
• All Positive Transition Filter registers are unaffected: Communicate, Hardware #1,
Hardware #2, Operation, Calibration,Call Processing and Questionable Data/Signal.
• The contents of the RAM memory are unaffected.
*RST IEEE 488.2 Common Command
The *RST Reset is accomplished by sending the *RST Common Command to the
Test Set through the GPIB bus.
For the CONFIGURE, PRINT CONFIGURE, TESTS (Execution Conditions),
TESTS (Printer Setup) and I/O CONFIGURE screens,
Table 30 lists the fields
which are restored/initialized when the *RST command is received. The restored
state or initialized value is listed below the field name. Fields which are not listed
are maintained at their current value, whatever that may happen to be. All fields in
the TESTS (Main Menu) screen and the TESTS (External Devices) screen are
maintained at their current state/value. The current state/value of the maintained
fields can be ascertained programmatically.
