Calculate[1|2|3|4]:Marker:harmonic:fundamentalcommand/Query - Agilent Technologies 35670A Manual

Common Commands
The setting last specified with *SRE is saved in nonvolatile memory. It can be recalled at power-up,
depending on the setting of the Power-on Status Clear flag (set with *PSC). When the flag is 0 at
power-up, all bits in the Service Request enable register are set according to the saved *SRE value.
When the flag is 1 at power-up, all bits in the Service Request enable register are initialized to 0.
The query returns the current state of the Service Request enable register. The state is returned as a sum
of the decimal weights of all set bits.
