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.
