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
PULSE MEASUREMENT NOISE (typical rms noise, R
DUT
<10
W): ±(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 .
** 8nV/ Hz for ranges above 10mV . meas_time (seconds) = pulsewidth – pulse_meas_delay in 33µs incr .

(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 .
