CALCulate<Ch/Tr>:LIMit:TTLout<Output_no>[:STATe] <Boolean>
Switches the TTL pass/fail signals on or off. The signals are applied to the USER CONTROL connector
as long as the active trace <Ch/Tr> is within limits.
<Ch/Tr> Channel number used to identify the active trace.
<Output_no>
1 – TTL out pass 1 (pin 13 of USER CONTROL connector)
2 – TTL out pass 2 (pin 14 of USER CONTROL connector)
<Boolean> ON | OFF - TTL output signal on or off.
*RST value OFF
SCPI, Command
Types Device-specific, command or query.
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.
CALCulate<Ch/Tr>:LIMit:UPPer[:DATA]
<numeric_value>,<numeric_value>{,<numeric_value>,<numeric_value>}
Defines the response (y-axis) values of the upper limit line and/or creates new limit line segments.
The commands
CALCulate<Ch/Tr>:LIMit:LOWer[:DATA]
and
CALCulate<Ch/Tr>: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:
ƒ
An odd number of values is rejected; an error message –109,"Missing parameter..." is
generated.
ƒ
An even number of 2*k values updates or generates k upper limit line segments.
ƒ
For n > k the response values of all existing upper limit line segments no. 1, 3, ...,2*k–1 are
updated, the existing upper and lower limit line segments no. 2*k+1, ..., 2*n are deleted. The
existing lower limit line segments no. 2, 4, 2*k are not affected.
ƒ
For n < k the response values of the upper limit line segments no. 1, 3 to 2*n–1 are updated,
the upper limit line segments 2*n+1, 2*n+3,..., 2*k–1 are generated with default stimulus values
(see
CALCulate<Ch/Tr>:LIMit:CONTrol[:DATA]
. In addition, the missing lower limit line
segments 2*n+2, 2*n+4,..., 2*k are generated with default stimulus and response values
