OUTPut:TTL:FEED <calculate_block>
Sets the calculate block whose limit handling controls the TTL voltage. If the measured
value of this calculate block violates a limit and limit monitoring is active, the voltage
specified in
​
table 6-14
​
Voltage at TTL output (first line) is output.
Parameters:
<calculate_block> string
Range:
"CALC1:LIM","CALC2:LIM","CALC3:LIM","CALC4:L
IM"
*RST: "CALC1:LIM"
OUTPut:TTL:HVOLtage <high_voltage>
Sets the high voltage for the TTL output.
Parameters:
<high_voltage> float_value
Range:
0 V to 3.3 V
*RST: 3.3 V
Default unit: V
OUTPut:TTL:LVOLtage <low_voltage>
Sets the low voltage for the TTL output.
Note: The value for the lower TTL level may be greater than the value for the upper TTL
level.
Parameters:
<low_voltage> float_value
Range:
0 V to 3.3 V
*RST: 0 V
Default unit: V
OUTPut:TTL[:STATe] <state>
Activates/deactivates the TTL operating mode of the OUT1 connector (rear panel). The
magnitude of the two possible output voltages can range from 0 V to 3.3 V
(
OUTP:TTL:HVOL
and
OUTP:TTL:LVOL
). Refer to
​

Voltage at TTL output to determine which voltage is available
at the output.

OUTP:TTL:ACT LOW
(OUTP:TTL:FAIL HIGH)
OUTP:TTL:ACT HIGH
(OUTP:TTL:FAIL LOW)
Measured value violates limit OUTP:TTL:LVOL OUTP:TTL:HVOL
Measured value is within limit OUTP:TTL:HVOL OUTP:TTL:LVOL
