Agilent Technologies Model A.08.xx manual Standard Event Status Event Enable Register

Status Registers

Use Status Registers to Determine the State of Analyzer Events and Conditions

Bit	Decimal	Description
	Value
5	32	Command Error: A 1 in this bit position indicates that a
		command error has occurred. Command errors have SCPI error
		numbers from –199 to –100.
6	64	User Request Key (Local: A 1 in this bit position indicates
		that the LOCAL key has been pressed. This is true even if the
		analyzer is in local lockout mode.
7	128	Power On: A 1 in this bit position indicates that the analyzer has
		been turned off and then on.

Standard Event Status Event Enable Register

The event enable register (contained in the standard event status register) lets you choose which bits will set the summary bit (bit 5 of the status byte register) to 1. Send the *ESE <number> command (where <number> is the sum of the decimal values of the bits you want to enable).

For example, to enable bit 7 and bit 6 so that whenever either of those bits is set to 1, the standard event status summary bit of the status byte register will also be set to 1, send the *ESE 192 (128 + 64) command. The *ESE? command returns the decimal value of the sum of the bits previously enabled with the *ESE <number> command.

STATus:OPERation Register

The STATus:OPERation register is used to determine the specific event that sets bit 7 in the status byte register. This register also monitors the current measurement state and checks to see if the analyzer is performing any of these functions:

•measuring

•calibrating
