Features:
- Seven functions: dcV, acV, dcI, acI, ohms, frequency, and period
- Three plug-in multiplexer options
- dc sensitivity to 10 nanovolts
Memory: 6235 available bytes that can be partitioned into 3
segments, one devoted to storing measurements, one devoted to storing measurement
subprograms, and one devoted to storing instrument states.
Math Functions: The HP 3547A performs the following math
functions on measurements: NULL, SCALE, OFFSET, RMS FILTER, SINGLE POLE FILTER, THERMISTOR
LINEARIZATION, DB, DBM, % ERROR, PASS/FAIL, LIMIT TESTING, and STATISTICS. Two math
functions may be used at one time.
