KEITHLEY 236 Source-Measure Unit

The Keithley 236 Source-Measure Unit is four instruments in one (voltage source, voltage measure, current source, and current measure). Measurements can be taken and recorded in an internal memory along with corresponding values of the source voltage or current and time. Up to 1000 values of each variable, correlated in time, may be accessed by the front panel using either a rotary dial or a keypad. All measurement and source values along with the elapsed time may also be obtained over the IEEE-488 bus.

Wideband Noise: 0.1 to 20M Hz, 8 mV p-p typical.
Overshoot: <0 .01 % (110V step, 10mA range).
Settling Time: <500 µs to 0.01 % (110V step, 10mA range).

Source Voltage Range Maximum Value: ±1.1000 V.
Source Step Size: 100 µV.
Source Accuracy (1 Year, 18 to 28 C): ± (0.033% + 650 µV + [output current/selected full scale current] x 450 µV).
Measure Resolution: 100 µV (4-digit), 10 µV (5-digit).
Measure Accuracy (1 Year, 18 to 28 C): ± (0.028% + 300 µV + [output current/selected full scale current] x 450 µV).

Source Voltage Range Maximum Value: ±11.000 V.
Source Step Size: 1 mV.
Source Accuracy (1 Year, 18 to 28 C): ± (0.033% + 2.4 mV.
Measure Resolution: 1 mV (4-digit), 100 µV (5-digit).
Measure Accuracy (1 Year, 18 to 28 C): ± (0.025% + 1 mV).

Source Voltage Range Maximum Value: ±110.00 V.
Source Step Size: 10 mV.
Source Accuracy (1 Year, 18 to 28 C): ± (0.033% + 24 mV).
Measure Resolution: 10 mV (4-digit), 1 mV (5-digit).
Measure Accuracy (1 Year, 18 to 28 C): ± (0.025% + 10 mV).

*This is a Web introductory price for one calibration of the KEITHLEY 236. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

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