   The Keithley 236, SourceMeasure Units (SMU) is a fully programmable instrument, capable of sourcing and measuring voltage or current simultaneously. These systems are really four instruments in one: voltage source, current source, voltage measure, and current measure.

Applications

   These instruments address a wide variety of applications, including the characterization of semiconductor devices and the measurement of leakage currents or insulation resistance. They are particularly useful as source and measuring instruments in automated test equipment (ATE).

Wide Dynamic Range

   The Model 236 will source voltage from 100µV to 110V, and current from 100fA to 100mA. It can also measure voltage from 10µV to 110V and current from 10fA to 100mA.

Selectable Sweeps of Voltage and Current

   The 236 can be programmed to perform source measurements as a function of a stepped voltage or current. Voltage and current can be swept linearly, logarithmically, or pulsed. The START, STOP, STEP method of setting sweep parameters allows operators to become proficient at using the instrument very quickly. Sweep parameters may be appended (APPEND key) to obtain more complex test sequences.

Features four instruments in one (voltage source, voltage measure, current source, current measure)

  • 10fA, 10µV measurement sensitivity
  • Standard and custom sweep capability including pulse
  • 21 source/measurements per second
  • Four quadrant source operation
  • Internal 21 reading memory

What is an electrometer?

   Essentially, an electrometer is a highly refined digital multimeter (DMM). Electrometers can be used for virtually any measurement task that a conventional DMM can and offer the advantages of very high input resistance when used as voltmeters, and ultralow current sensitivity with low voltage burden when used as ammeters. Electrometers are superior to DMMs by three to eight orders of magnitude in these respects. That makes them the instruments of choice for measuring voltages with high source impedance or currents with low source impedance (i.e., signals from nonideal sources). Electrometers can also measure charge directly.
