• Maximum output: ±210V/±1.05A/22W
• This version includes GPIB
• Four quadrant source and sink operation
• First and third quadrants operate as power supplies to supply power to the load
• Second and fourth quadrants function as loads to consume power internally

The Instek GSM-20H10 is a precision source measure unit that provides highly stable DC power and instrument-grade 6.5-digit multimeter measurements. While operating, it can be used as a voltage source, current source, voltmeter, ammeter, and ohmmeter, making it ideal for the evaluation of component characteristics and a variety of test applications.

Four quadrant operation

The GSM-20H10 provides a four-quadrant operation of ±210V/±1.05A/22W. The first and third quadrants operate as power supplies to supply power to the load. The second and fourth quadrants function as loads to consume power internally. Voltage value, current value, and resistance value can be measured while operating the power supply or load function with an accuracy of 0.012% and a resolution of 1µV/10pA/10µΩ.

• ± 21V / ± 1.05A
• ± 210V / ± 105mA
• 22W power capacity

The GSM-20H10 provides measurement accuracy of up to 0.012%, and provides a meter display function of up to 6½ digits, allowing users to have more accurate results when measuring small signals. Measurement resolution of 1µV/10pA/10µΩ.

The SDM (Source Delay Measure) function is provided to delay sampling when the signal changes to prevent the unstable signal from being captured and causing misjudgment. There are four built-in sequence output modes (Linear stair, Log stair, SRC-MEM, Custom), which can support up to 2500 points of sequence variation output.

In addition to 2 wires, the GSM-20H10 also provides 4-wire and 6-wire resistance measurements.

4-wire measurement eliminates the effect of lead resistance, realizing accurate measurement of small resistances below 100ohm at high currents.

6-wire combining 4-wire connection and the protection of ohm characteristics eliminates the effects of internal parallel resistance, realizing the resistance measurement of a tiny wire.
