Description
“ACQ_LOG_RESET”
“OK”
Resets (clears) the sample
buffers. Also arms the envelope
trace measurement, waiting for
the next valid trigger.
“ACQ_LOG_STATUS?”
“0” or “1”
0 = waiting for trigger
1 = buffers filled
“ACQ_LOG_DATA?”
Power values from
buffer samples 0 to
1000
Returns log power values from
buffer in dBm (ASCII text dump,
values are separated by a “;”).
“ACQ_LOG_DATA_ENH? <i>,<j>”
Power values from
buffer <i> samples
before trigger to <j>
samples after trigger.
Returns log data from pre and or
post trigger buffer (text dump).
Buffer sizes <i> and <j> can be 0
to 2000
“ACQ_LOG_DATA_ENH_BIN?
<i>,<j>”
Power values from
buffer <i> samples
before trigger to <j>
samples after trigger.
Returns log data from pre and/or
post trigger buffer (binary dump,
2 byte integer *100) special code
0x7777 represents data start,
0xAAAA represents data end.
“ACQ_LOG_THRESHOLD <l>”
“OK”
Sets the trigger level to power
level <l> in dBm.
“ACQ_LOG_THRESHOLD?”
“-40.00”
Returns trigger level.
“ACQ_LOG_TRIGGER <a>,<b>,<c>” “OK”
Sets trigger mode:
<a> = 0 (for Edge triggering)
<a> = 1 (for Level triggering)
<b> = 0 (for Falling edge)
<b> = 1 (for Rising edge)
<c> = 2 to 10 (for number of
samples used to evaluate edge or
level trigger)
During edge trigger the distance
between two samples is 10,
during level trigger the distance
between to samples is 1.
“ACQ_LOG_TRIGGER?”
Returns trigger settings
<a>;<b>;<c>
<a> = mode
<b> = rising/falling edge
<c> = trigger filter
