GPIB Service Mnemonic Definitions
All service routine keystrokes can be made through GPIB in one of the following
approaches:
• sending equivalent remote GPIB commands (Mnemonics have been documented
previously with the corresponding keystroke.)
• invoking the System Menu (MENUSYST) and using the analyzer mnemonic (SOFTn),
where “n” represents the softkey number. (Softkeys are numbered 1 to 8 from top to
bottom.)
An GPIB overview is provided in the “Operating Concepts” chapter in the analyzer user’s
guide. GPIB programming information is also provided in the programmer’s guide.
Invoking Tests Remotely
Many tests require a response to the displayed prompts. Since bit 1 of the Event Status
Register B is set (bit 1 = service routine waiting) any time a service routine prompts the
user for an expected response, you can send an appropriate response using one of the
following techniques:
• Read event status register B to reset the bit.
• Enable bit 1 to interrupt (ESNB[D]). See “Error Reporting” of the analyzer
programmer’s guide.
• Respond to the prompt with a TESRn command (see “Tests Menu” on page 10-5).
