Query the Mechanical Relay Cycle Count
Return the count of mechanical relay cycles. For N9038A model, there are additional 2 Mechanical Relays which
are <N9038A Input2>, <N9038A Bypass>.
Query the Operating Temperature Extremes
Returns the low operating temperature extreme value. The value survives a power-cycle and is the temperature
extreme encountered since the value was reset by the factory or service center.
Remote Command: :SYSTem:MRELay:COUNt?
Example: :SYST:MREL:COUN?
Notes: Query Only
The return value is a comma separated list of the individual counts for each
mechanical relay.
The position of the relays in the list is:
“<Cal Signal>,<AC/DC>,<2dB #1 Atten>,<2dB #2 Atten>,<6dB
Atten>,<10dB Atten>,<20dB Atten>,<30dB Atten>,<Fixed Atten>,<Low
Noise Path Switch>,<Presel Bypass>,<N9038A Input2>, <N9038A Bypass>”
Items in the list not pertaining to your particular hardware configuration will
return as –999 for those items.
Dependencies: This SCPI command is NOT supported by the E6607C model.
