●
The signals are switched on as soon as a measurement (sweep) in a channel with
non-zero channel bits is started. They are changed whenever a channel with differ-
ent channel bits becomes the measuring channel.
●
The signals at the User Port connector are maintained after the analyzer enters the
hold state. This happens if all channels use single sweep mode and if all sweep
sequences have been terminated.
●
Pins 16 to 19 may be reserved for monitoring the drive ports 1 to 4 of the analyzer
(
). This leaves up to 16 different monitored channel
states.
Tip:
A simple application consists of selecting the channel numbers as parameters for
CONTrol:AUXiliary:C[:DATA]
and monitor the activity of up to 255 different chan-
nels at the User Port connector; see example below. You can also use the User Port
output signals as channel-dependent trigger signals for external devices. Use
to transfer the eight bit value for an arbitrary channel
<Ch> in binary representation.
Parameters:
<DecValue>
Decimal value. The values correspond to the following states of
the User Port connector:
0 - no signal at any of the no signal at any of the eight pins 8, 9,
10, 11, 16, 17, 18, 19
1 - output signal at pin 8
2 - output signal at pin 9
3 - output signal at pins 8 and 9
...
255 - output signal at pins 8, 9, 10, 11, 16, 17, 18, 19
Range:
0 to 255
*RST:
0 (no signal)
Example:
*RST; :CONT:AUX:C 1
Assign the channel bit value 1 to the active channel no. 1. The
analyzer performs a measurement in channel no. 1, therefore
the output signal at pin 8 is switched on.
CONF:CHAN2:STAT ON; :CONT:AUX:C 2
Create channel no. 2, causing it to become the active channel,
and assign the channel bit value 2. The analyzer performs no
measurement in channel no. 2, therefore the output signal is not
changed.
CALC2:PAR:SDEF 'Ch2Tr1', 'S11'
Create a trace named 'Ch2Tr1' and assign it to channel 2. While
the analyzer measures in channel 2, the output signal changes
from pin 8 to pin 9.
