HP 5005B Signature Multimeter

In a single instrument, the HP 5005B signature multimeter offers an entire measurement set optimized for digital troubleshooting applications. The HP 5005B reduces complicated bit streams into four-character words. These words, or signatures, provide a fingerprint of data activity with greater than 99.998-percent confidence of fault detection, regardless of the data stream length.

The HP 5005B includes capabilities for checking power supplies and circuit board integrity, universal counter features for measuring clock frequencies and time intervals between signals, and a means for verifying the analog integrity of active digital signals.

Performance

Analog circuit failures such as low power supply voltage, an open or shorted circuit path, or a faulty A/D or D/A converter can cause digital problems. The HP 5005B contains a 4.5-digit dc voltmeter, ohmmeter, and differential voltmeter to help pinpoint system failures.

Counter functions

Totalize and frequency measurements can be made to 50 MHz, and time interval measurements are made with 100 nanosecond resolution. Functions can characterize one-shots and timers, test interrupt lines, reset line and RS-232 asynchronous interfaces, and verify clock and clock driver circuitry.

Voltage threshold

The peak voltage measurement mode provides a simple, direct method for measuring the logic high and logic low voltages of active digital signals. The HP 5005B can characterize and display either the greatest (positive peak) or lowest (negative peak) voltage probed for comparison against the specifications of the logic family.

Composite signatures

Signatures for digital signal groups and stored signatures allow for quicker, more accurate reference comparisons.

Multifunction

Automated access to signature analyzer, multimeter, and counter functions is provided through a single, multifunction probe. Signal multiplexing to the appropriate function is internal to the HP 5005B.
