OUTPut:TTL[1]:STATe[?] ON | OFF
Activates (ON) or deactivates (OFF) 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 ÆTable 6-9 and Æ Figure 6-6 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
