Procedure

Preparation

1. Create a sweep pattern (source pattern) used to vary collector-emitter voltage

of the transistor using a general-purpose spreadsheet application on your

PC. (If the amount of voltage change is constant, you can also use the linear

sweep (see section 6.1, “Setting the Log or Linear Sweep”).)

2. Save the pattern sweep data that you created in step 1 to a file in CSV format.

3. Transfer (Copy) the pattern sweep data file to the internal memory

(GS610ROM) of the first GS610 via the USB.

4. Set each GS610 as follows:

SOURCE Output function Voltage output Current output

Limiter value 150 mA 1 V

Output mode DC DC

Output range: AUTO AUTO

OUTPUT CONTROL Trigger mode Internal Internal

Sweep mode Program OFF

(of the internal trigger)*

Repeat period of the internal trigger > Output delay + measure delay + integration time + α.

(α = Time caused by range change, calibration, and so on)
