These commands are used to specify trigger levels for the specified (current or voltage) input
signal. An appropriate trigger level is necessary in order for the frequency counter to operate
properly. The instrument only counts cycles whose peak signal amplitude reaches the pro-
grammed trigger level. See paragraph 2.4.4 (Trigger Level) for more information.
PRINT #1, "output 16; freq:thr:curr:rang .01"
PRINT #1, "output 16; freq:thr:curr:lev .005; lev?"
PRINT #1, "enter 16"
:TTL
[:SENSe[1]]:FREQuency:THReshold:VOLTage:TTL
This action command is used to configure the voltage trigger level for a TTL input signal. After
this command is sent, the 10V threshold voltage range is selected and a threshold trigger level
of 0.8V is established.
PRINT #1, "output 16; freq:thr:curr:volt:ttl"
PRINT #1, "output 16; freq:thr:volt:rang?; lev?"
PRINT #1, "enter 16"

:TRANsducer? Query transducer type
This command is used to program the instrument for the transducer type that you are using. If
using a two-wire RTD transducer, select RTD. If using a three-wire or four-wire RTD, select
FRTD. If using a thermocouple, select TCouple. Select DTC if performing differential TC tem-
perature measurements using the Model 1801 Nanovolt Preamp.
Use the INTernal transducer to measure the internal temperature difference from the calibration
temperature of the Model 2002.
