主要特點及優(yōu)點快速且極低噪聲

2182 納伏表吉時利產品詳情

主要特點及優(yōu)點
•快速且極低噪聲，15nVP-P 噪聲@1s 響應時間，40-50nV p-p噪聲@60s 響應時間
•Delta模式測量，配合程控電流源反轉極性進行低阻測試，可達24Hz和30nV P-P噪聲，多次讀數(shù)平均還可進一步降低噪聲
•與電源同步技術可提供110dB的串模抑制 (NMRR) ，將AC共模電流的影響減至最小
•雙通道輸入，可測量電壓、溫度或未知電阻與參考電阻的比例

ANALOG OUTPUT
MAXIMUM OUTPUT: ±1.2V.
ACCURACY: ±(0.1% of output + 1mV).
OUTPUT RESISTANCE: 1kΩ ±5%.
GAIN: Adjustable from 10-9 to 106. With gain set to 1, a full range input will produce a 1V output.
OUTPUT REL: Selects the value of input that represents 0V at output. The reference value can be either programmed value or the value of the previous input.

TRIGGERING AND MEMORY
WINDOW FILTER SENSITIVITY: 0.01%, 0.1%, 1%, 10%, or full scale range (none).
READING HOLD SENSITIVITY: 0.01%, 0.1%, 1%, or 10% of reading.
TRIGGER DELAY: 0 to 99 hours (1ms step size).
EXTERNAL TRIGGER DELAY: 2ms + <1ms jitter with auto zero off, trigger delay = 0.
MEMORY SIZE: 1024 readings.

MATH FUNCTIONS
Rel, Min/Max/Average/Std. Dev/Peak-to-Peak (of stored reading), Limit Test, %, and mX+b with user defined units displayed.

VOLTS SPECIFICATIONS (20% OVER RANGE)

CONDITIONS: 1PLC with 10 reading digital filter or 5PLC with 2 reading digital filter.

ACCURACY: ±(ppm of reading + ppm of range)

(ppm = parts per million) (e.g., 10ppm = 0.001%)

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 24XX series or 622X series 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. 1 Hz achieved with 1PLC, delay = 1ms, RPT filter = 23 (20 if 50Hz)

PULSE-MODE (with 6221):

line synchronized voltage measurements within current pulses from 50us to 12ms, pulse repetition rate up to 12 Hz

Pulse measurement noise:

(typical RMS noise, RDUT<10 ohms) (0.009ppm of range*)/meas_time/√pulse_avg_count + 3nV/√(2 · meas_time · pulse_avg_count) for 10mV range**

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.
