To calibrate dual output V/V:
1. Connect the phase meter REFERENCE INPUT to the Product OUTPUT VZ HI/LO with the double
banana RG58 cable and BNC (M) to the binding post adapter.
2. Connect the phase meter SIGNAL INPUT to the Product SENSE VZ LO/VI AUX with the double
banana RG58 cable and BNC (M) to the binding post adapter. Use the same length cables for both.
3. Start with step 1, Table 27, source the specified phase with specific signal and frequency
parameters from the Product.
4. Measure with the phase meter and record in the Measured Product Output column.
5. Continue with the remainder of the steps in Table 27.

Voltage/Current output requires the placement of a current shunt between the Product and the phase
meter SIGNAL INPUT.
Failure to connect a shunt may result in phase meter damage.
To calibrate dual output V/I:
1. Connect phase meter REFERENCE INPUT to the Product OUTPUT VZ HI/LO with the double
banana RG58 cable and the BNC (M) to the binding post adapter.
2. Connect the phase meter SIGNAL INPUT to the A40B-100mA shunt output with the appropriate
cable and adapters.
3. Connect the shunt input to the Product SENSE VZ LO/VI AUX with the A40B-LEAD/4mm. Use the
cable with such a length that the total length of shunt and cable is approximately the length of the
cables used for the REFERENCE INPUT.
