   Keysight (Agilent) 3478A   Description / Specification:    
Keysight (Agilent) 3478A 3 1/2 to 5 1/2 Digit Digital Multimeter

The HP 3478A provides a low cost, completely HP-IB programmable solution for system measurements. Selectable 3 1/2 to 5 1/2 digit resolution and 5 autoranging functions offer flexibility in automated testing. The HP 3478A can measure DCV, true RMS ACV, 2 and 4 wire ohms, and DC and AC current. The HP 3478A can perform production tests or acquire experimental data at 71 readings/sec with 3 1/2 digit resolution, or take 33 readings/sec with 130 dB of noise rejection using 4 1/2 digits. The 5 1/2 digit mode offers 100 nVDC and 100 micro-ohm resolution for precise measurements. True RMS with 300 kHz bandwidth and 4:1 crest factor provides reliable measurements of AC signals. Fast autoranging makes the first reading useful and accurate. Specifications. DC Voltage Maximum Reading: ±303.099 V. DC Voltage Resolution: 100 nV to 100 mV. AC Voltage (true rms) Maximum Reading: ±303.099 V. AC Voltage (true rms) Resolution: 1 uV to 100 mV. DC Current Maximum Reading: ± 3.03099 A. DC Current Resolution: 1 uA to 1 mA. AC Current (true rms) Maximum Reading: 3.03099 A. AC Current (true rms) Resolution: 1 uA to 1 mA. Resistance (2-wire ohm 4-wire ohm) Maximum Reading: 30.3099 M-ohm. Resistance (2-wire ohm 4-wire ohm) Resolution: 100 micro-ohn to 10 k-ohm.

Clipping
Clipping is the limiting of a signal so that it never exceeds some threshold.

Line Regulation
Line regulation is the capability to maintain a constant output voltage level on the output channel of a power supply despite changes to the input voltage level.

Peak Envelope Power
Peak envelope power is the maximum value of the envelope power. Envelope power is measured by making the averaging time much less than 1/fm where fm is the maximum frequency component of the modulation waveform. The averaging time is therefore limited on both ends: (1) it must be small compared to the period of the highest modulation frequency, and (2) it must be large enough to be many RF cycles long.

RMS
RMS or root mean square is a statistical measure of the magnitude of a varying quantity
