B/A Function - Arbiter Systems 928A User Manual

B/A Function

Use the B/A function in the same manner as you would
with the A/B, only with the reverse response as with
the A/B function and the same input signals.
Use the B/A function to find the ratio of the two
measured input signals to Channels A and B. If, for
example, you wish to know the ratio of a voltage at
channel A to a current a channel B, pressing the B/A
button will display the results of dividing the current
by the voltage giving conductance, in Mhos, and phase
offset of Channel A from Channel B, in degrees.
Setup
1. Press B A and connect the measurement probes
to the circuit under test.
2. Read the display.
NOTES: If you configure channel A as current and
channel B as voltage, the units will be in ohms and
degrees. If you choose two voltages or two currents,
then the units will be a strict ratio (with no displayed
units for B/A) and degrees.
