Đồng hồ vạn năng để bàn độ chính xác cao, dãy đo rộng Keithley 2182A Digital Nanovoltmeter & Low Voltage Meters

Tổng quan thiết bị:

– Make low noise measurements at high speeds, typically just 15nV p-p noise at 1s response time, 40 -50nV p-p noise at 60ms

– Delta mode coordinates measurements with a reversing current source at up to 24Hz with 30nV p-p noise (typical) for one reading. Averages multiple readings for greater noise reduction

– Synchronization to line provides 110dB NMRR and minimizes the effect of AC common-mode currents

– Dual channels support measuring voltage, temperature, or the ratio of an unknown resistance to a reference resistor

– Built-in thermocouple linearization and cold junction compensation

CHANNEL 1/CHANNEL 2 RATIO For input signals =1% of the range, Ratio Accuracy = ±{[Channel 1 ppm of Reading + Channel 1 ppm of Range * (Channel 1 Range/Channel 1 Input)] + [Channel 2 ppm of Reading + Channel 2 ppm of Range * (Channel 2 Range/Channel 2 Input)]}.
DELTA (hardware-triggered coordination with Series 24XX, Series 26XXA, or Series 622X current sources for low noise R measurement) Accuracy = accuracy of selected Channel 1 range plus accuracy of I source range.
DELTA MEASUREMENT NOISE WITH 6220 or 6221 Typical 3nVrms / Hz (10mV range) 21 . 1Hz achieved with 1PLC, delay = 1ms, RPT filter = 23 (20 if 50Hz)
PULSE-MODE (WITH 6221) Line synchronized voltage measurements within current pulses from 50µs to 12ms, pulse repetition rate up to 12Hz.
PULSE MEASUREMENT NOISE (typical rms noise, R DUT <10Ω) ±(0.009ppm of range*) / meas_time / pulse_avg_count + 3nV** / (2 · meas_time · pulse_avg_count) for 10mV range.
* 0.0028ppm for the 100mV range, 0.0016ppm for ranges 1V and above.
** 8nV/ Hz for ranges above 10mV . meas_time (seconds) = pulsewidth – pulse_meas_delay in 33µs incr.
DC Noise Performance (DC noise expressed in volts peak-to-peak)
Response time = time required for reading to be settled within noise levels from a stepped input, 60Hz operation.
