CALCulate<Chn>:LIMit:TTLout<Pt>[:STATe]
<Boolean>
Switches the TTL pass/fail signals on or off. The signals are applied to the USER PORT
connector as long as the active trace
<Chn>
is within limits, including the ripple limits.
Suffix:
<Chn>
.
Channel number used to identify the active trace.
<Pt>
1 - TTL out pass 1 (pin 13 of USER PORT connector)
2 - TTL out pass 2 (pin 14 of USER PORT connector)
Parameters:
<Boolean>
ON | OFF - TTL output signal on or off.
*RST:
OFF
Example:
*RST; :CALC:LIM:CONT 1 GHZ, 2 GHZ
Define an upper limit line segment in the stimulus range between
1 GHz and 2 GHz, using default response values.
CALC:LIM:STAT ON; TTL2 ON
Switch the limit check on and activate the TTL out pass 2 signal.
Manual operation:
See
CALCulate<Chn>:LIMit:LOWer[:DATA]
<LimitLineSegm>, <LimLineSegm>...
CALCulate<Chn>:LIMit:UPPer[:DATA]
<Response>, <Response>...
Defines the response (y-axis) values of the lower or upper limit line and/or creates new
limit line segments. See also
chapter 3.4.1.1, "Rules for Limit Line Definition"
Note:
The commands
CALCulate<Ch>:LIMit:LOWer[:DATA]
and
CALCulate<Ch>:LIMit:UPPer[:DATA]
use a fixed numbering scheme for limit line
segments: Upper limit line segments are assigned odd numbers (1, 3, 5,...), lower limit
line segments are assigned even numbers (2, 4, 6,...).
Rules for creating segments
The following rules apply to an active trace with n existing upper and n existing lower limit
line segments:
●
An odd number of values is rejected; an error message -109,"Missing parameter..."
is generated.
●
An even number of 2*k values updates or generates k lower limit line segments.
●
For n > k the response values of all existing lower limit line segments no. 2, 4 ... 2*k
are updated, the existing upper and lower limit line segments no. 2*k+1 ... 2*n are
deleted. The existing upper limit line segments no. 1, 3, 2*k-1 are not affected.
●
For n < k the response values of the lower limit line segments no. 2, 4 to 2*n are
updated, the lower limit line segments 2*n+2, 2*n+4 ... 2*k are generated with default
stimulus values (see
In addition, the missing upper limit line segments 2*n+1, 2*n+3 ... 2*k-1 are generated
with default stimulus and response values
Suffix:
<Chn>
.
Channel number used to identify the active trace.
