Photocurrent Amplifier.
PCA 1000 Series
The PCA is a compact and versatile photodiode amplifier, designed to precisely measure photocurrent.
It provides both analog and digital transimpedance amplifiers for photodiode currents ranging from 10 nA to 2 mA and offers fully adjustable bias voltage control and adjustable frequency response for flexibility. Its single-slot PXIe form factor enables convenient backplane triggering and it is compatible with a wide range of optical and electrical PXI test modules.
Digital & analog photocurrent measurement
Allows precise control of the PD under test to measure dark current and characterize its responsivity.
Analog logarithmic transimpedance photocurrent amplifier
Amplify your PD current to provide a high gain signal via the SMA connector.
Configurable frequency response
Digital control of the frequency response of the analog output from 1 MHz down to 100 Hz.
Adjustable reverse bias voltage
Optimize the bias voltage in 0.01 V increments from 0 to 10 V to properly bias the PD.
Triax input connector for low current measurement
Make precise low current measurements.
Supports photodiode responsivity calibration
Use the PCA as an optical power meter by converting PD current to equivalent optical Power in mW or dBm.
