Using the figure Programmable Gain Input Amplifier (PGIA) (p. 349), for reference,
during a differential measurement, the high signal (H) is routed to V+ and the low
signal (L) is routed to V–.
An H terminal of an H/L terminal pair differential corresponds to V+. The L
terminal corresponds to V–. The differential configuration is used with the
following CRBasic instructions:
• VoltDiff()
• BrFull()
• BrFull6W()
• BrHalf4W()
• TCDiff()
