CHANNEL ANALOG OUTPUT
The T703 calibrator comes equipped with one analog output. It can be set by the user to carry the current signal
level of any one of the parameters listed in Table 6-8 and will output an analog VDC signal that rises and falls in
relationship with the value of the parameter.

RANGE
1
: Selects the DCV full-scale value of the output.
OVERRANGE: Turns the ± 5% over-range feature ON/OFF for this output channel.
REC_OFS
REC_OFS
1
: Sets a voltage offset (not available when RANGE is set to CURRent loop.
AUTO_CAL
1
: Sets the channel for automatic or manual calibration
CALIBRATED
1
: Performs the same calibration as AOUT CALIBRATED, but on this
one channel only.
AIN CALIBRATED
Shows the calibration status (YES/NO) and initiates a calibration of the analog to digital
converter circuit on the motherboard.

Changes to RANGE or REC_OFS require recalibration of this output.
To configure the analyzer’s TEST CHANNEL, set the electronic signal type of each channel and calibrate the
outputs. This consists of:
outputs. This consists of:
1. Choosing
a
TEST CHANNEL function to be output on the channel.
2. Selecting a signal level that matches the input requirements of the recording device attached to the
channel.
3. Determining if the over-range feature is needed and turn it on or off accordingly.
4. Adding a bipolar recorder offset to the signal if required (Section6.9.1.5).
5. Calibrating the output channel. This can be done automatically or manually for each channel (see
Sections 6.9.2).
