• The multimeter at secondary address 03 (logical address 24) is
connected to the switchbox at secondary address 14 (logical
address 112) with an analog bus cable and a digital bus cable.
• The analog bus carries the input signals to the multimeter. The
digital bus is used to carry a "multimeter complete" signal to the
switchbox to trigger the next channel closing.
• Because of the fast rate at which the FET channels close, the
multimeter is triggered once (
INIT) and then samples continuously
(
SAMP:COUN 500). Thus, the multimeter ignores the multiplexer
"channel closed" signal on the digital bus.
• Using this configuration, the multimeter is able to continuously scan the
switchbox and store readings in its memory at a 76 µs (13 kHz) rate.
