The GS820 Multi-Channel Source Meter comes in 18-volt and 50-volt models for testing LED lighting, measuring drain current, and more. It has two isolated analog channels, each with a constant voltage source, constant current source, voltmeter, and ammeter. The Yokogawa source measure unit, GS820 offers two sweep functions, PC connectivity via USB, and expansion up to 10 channels.
Applications:
- DC voltage/current reference
- I/V curve trace
- Semiconductor parametric test
- Pulse voltage/current source
- Electronic load
- Resistance measurement
- Programmable arbitrary
- Production test waveform generation
Source and Measurement Functions:
- Voltage source and current measurement (VS&IM)
- Current source and voltage measurement (IS&VM)
- Voltage source (VS)
- Current source (IS)
- Voltmeter (VM)
- Ammeter (IM)
- Resistance meter (IS&VM)
These functions can be selected for each channel to form an arbitrary combination of functions.
Four-quadrant operation consisting of source operation (current source) and sink operation (current sink) is available with ranges up to 7 V and 3.2 A or 18 V and 1.2 A. The output and measurement resolutions are 5.5 digits. Other features include:
