FDATa
Formatted trace data, according to the selected trace format (
). 1 value per trace point for Cartesian diagrams, 2 values for polar dia-
grams.
SDATa
Unformatted trace data: Real and imaginary part of each measurement point. 2
values per trace point irrespective of the selected trace format. The trace mathe-
matics is not taken into account.
MDATa
Unformatted trace data (see
SDATa
) after evaluation of the trace mathematics.
INSTrument[:SELect]
<Channel>
Selects a channel
<Ch>
as active channel. To select a channel number > 4 use the
.
Parameters:
<Channel>
CHANnel1 | CHANnel2 | CHANnel3 | CHANnel4
Number of the channel to be activated. The channel must be
created before using
ON
.
*RST:
CHANNEL1
Example:
CONF:CHAN2:STAT ON; :INST CHANnel2
Create channel no. 2 and select it as the active channel.
OUTPut<Chn>:DPORt
<Port>
Selects a source port for the stimulus signal (drive port). The setting acts on the active
trace. The effect of the drive port selection depends on the measurement parameter
associated to the active trace:
●
If an S-parameter S
<out><in>
is measured, the second port number index <in> (input
port of the DUT = drive port of the analyzer) is set equal to the selected drive port:
Drive port selection affects the measured quantity.
●
If a wave quantity or a ratio is measured, the drive port is independent from the
measured quantity:
Suffix:
<Chn>
.
Channel number used to identify the active trace
Parameters:
<Port>
PORT<no>
Physical port number.
*RST:
PORT1
Example:
CALC4:PAR:SDEF 'Ch4Tr1', 'A1'
Create channel 4 and a trace named "Ch4Tr1" to measure the
wave quantity a
1
. The trace automatically becomes the active
trace.
OUTP4:DPOR PORT2
Select drive port 2 for the active trace.
