?RBW This query command #?RBW * sends back a string expressing the selected RBW.
The reply is made of 3 fields:
1. RBW=AUTO (9010 automatically selects the suitable RBW according the
tuned frequency) or RBW=MAN ( Operator selects manually the RBW)
2. Id identify the RBW as follows:
o 1 300kHz
o 2 100kHz
o 3 30kHz
o 4 10kHz
o 5 3kHz
o Only for 9010
6 9kHz (Cispr 16-1)
7 200Hz (Cispr 16-1)
11 10kHz (MIL-STD-461) (only when available)
22 1kHz (MIL-STD-461) (only when available)
23 100Hz (MIL-STD-461) (only when available)
24 10Hz (MIL-STD-461) (only when available)
o Only for Downconverter
9 1MHz (Cispr 16-1)
10 120kHz (Cispr 16-1)
12 9kHz (Cispr 16-1)
3. RBW NickName (a mnemonic name)
Example of reply: RBW=AUTO 6 (9k_CISPR) which means that selection is
automatically made by 9010, the RBW id is 6 (9kHz (Cispr 16-1). (9k_CISPR) is
the nickname to quickly identify it
?S/N This query command #?S/N* sends back a string containing serial number
internally stored by manufacturer.
Example of reply: S/N=000WE50327
?SAT This query command #?SAT* sends back a string expressing the Attenuator status
for Sweep mode. The reply is made of 2 fields:
• SAT =AUTO (9010 automatically selects the most suitable attenuator to
get best dynamic range)
• Value (in dB) of current attenuator
Note: In Sweep mode the Attenuator is always forced to AUTO
Example of reply: SAT =AUTO; 20 which means that the Attenuator is now
switched to 20dB automatically by 9010
?SDT This query command #?SDT* sends back a string expressing the detector used for
Sweep mode. The reply is made of several field representing the mode and, in
case of smart detector function, the limit name and margin on which the smart
detector is based:
• SDT =Peak
• SDT =Peak
• SDT =Avg
• SDT =Rms
• SDT =C-Rms
• SDT =C-Avg
• SDT=Smart QPeak (CISPR 22-A +0dB)
?SHT This query command #?SHT* sends back a string expressing the HOLD TIME for
Sweep mode. Unit is fixed ms.
Example of reply: SHT= 1000 ms which means that the hold time in Sweep mode
is 1000ms (or 1s)
Note that the Hold Time is automatically changed when detector is set to Smart
mode. In this case when the command SSDT is received the Hold Time = Min(Hold
Time, 1000). If one wants to set it lower than 1000 in smart mode, the user should
send the hold time command (SSHT) later than SSDT command.
