The calibration is performed by calibration technicians. We have more then 30 years of experience in calibrating instruments. In short, your Keithley instrument is taken good care off! We focus on a fast lead time and extremely high standard of our service.
Keithley 2500 Photodiode Meter
The Model 2500 combines two stable DC bias voltage sources with two low-noise ammeters for dual-channel, low-current photodiode measurements. The unit has 0.1% basic measurement accuracy with up to 6½-digit resolution. At 5½-digit resolution, the Model 2500 can transfer up to 475 readings per second over the GPIB, and up to 900 readings per second with 4½-digit resolution.
Each Model 2500 channel has the following measurement and voltage bias capabilities:
• Measure current from 1fA to 20mA.
• Source bias voltage from 500µV to 100V.
Some additional capabilities of the Model 2500 include:
• Sweep capabilities: linear and logarithmic staircase, and custom sweeps of up to 2500 points.
• Two hardware limit tests and four software limit tests with a built-in comparator for/fail testing.
• Digital I/O for stand-alone binning operations or interface to component handler.
• Programming language and remote interfaces — The Model 2500 uses the SCPI programming language and two remote interface ports (IEEE-488/GPIB and RS-232C).
• Trigger-Link interface to Keithley Series 7000 switching hardware.
• Math functions — V/I, I/V, optical power, electrical power, ratio, delta, and offset functions.
• Reading and setup storage — Up to 3000 5½-digit readings for each channel and seven setups (five user defaults, factory default, *RST default) can be stored and recalled.
• Closed-cover calibration — The instrument can be calibrated either from the front panel or remote interface.
• The Model 2502 adds an analog output for each channel. Each analog output provides a -10V to +10V output voltage analogous to the input current.
