After being given a DATA:ISTA:VERB command, the apparatus transmits the samples
in the following format:
Fstart
<start_value> Hz,Fstop <stop_value> Hz,Fstep <step_value> Hz,N level
<levels number> ,dBuV/m=><0D><0A>
<data1>;<data2>;...<data n>
Where:
<start_value> = string containing the Hz value of the start frquency
<stop_value>
= string containing the Hz value of the stop frequency
<step_value> = string containing the step Hz value
<levels_number> = string containing the number of samples transmitted below, that
represent the number of acquired levels
< N date > string containing the level at F frequency
In order to determine the F frequency =
<start_value>+N x <step_value>
Example for receive:
Fstart 9.750e+07 Hz,Fstop 1.025e+08 Hz,Fstep 5.000e+04 Hz,N level 101.000000,V/m
