For BASIC REQUEST and PROPRIETARY REQUEST commands are made of
ASCII string delimited by the character
“*”
(0x2A) and the length is four characters
Replies are terminated with <CR><LF> (\r\n)
Applicable with the versions below or following:
-

-
every unsigned int will be contained in 2 bytes
BASIC REQUEST COMMANDS
Commands Description
IDN?
This command * IDN? gives version and date of the firmware, followed by
[0D][0A]
Example of reply: IDN=SEP-FW - B.37 20/10/17[0D][0A]
For a correct configuration of the units use in this sequence the command setting:
*IDN?
SENS:FREQ:STOP:<value of frequency>
SENS:FREQ:STAR:<value of frequency>
SENS:BAND:<filter RBW>
SENS:DETE:<detector type>
SENS:HOLD:<time for the hold>
SENS:AXIS:<name of axis>
DATA:ISTA:VERB
