GW Instek GSM-20H10 is a precision source meter that provides highly stable DC power and instrument-grade 6½-digit multimeter measurements. While operating, it can be used as a voltage source, current source, voltmeter, ammeter, and ohmmeter, which is uniquely ideal for the evaluation of component characteristics and the test applications of production, including nanomaterials and components, semiconductor architecture, organic materials, high-efficiency illumination, passive components and material characteristics' analysis, etc.

GSM-20H10 provides 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.

With respect to sampling rate, GSM-20H10 supports a sampling rate of up to 50k points/second, which can accurately analyze the characteristics of the DUT. With the large 4.3-inch screen, all measurement settings, parameters, and results can be completely displayed on the screen.

The SDM (Source Delay Measure) function is provided to delay sampling when the signal changes to prevent the unstable signal from being captured and cause 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.

Pertaining to protection, GSM-20H10 provides OVP/OTP modes. The design of OVP allows users to self-define the range of OVP. OTP can effectively prevent errors caused by temperature drift during the test process. For interfaces, this product supports standard SCPI commands and provides RS-232, USBTMC, LAN, GPIB (optional) interfaces to meet users’ different interface needs.

Maximum Output: ±210V/±1.05A/22W

The power source output of the GSM-20H10 has two ranges.
The voltage range is ±21 volts, and the current is ±1.05A.
The voltage range is ±210 volts, and the current range is ±105mA.
The power capacity is 22W.
Provide a full range of four-quadrant measurement without duty cycle limit.

Built-in 4 Sequence Output Modes, up to 2500 points

Built-in Sequence Output Modes, up to 2500 points

GSM-20H10 precision source meter provides four sequence output modes: linear staircase, log staircase, SRC-MEM (source memory) and Custom(self-defined).

With these output modes, users can quickly generate output as needed. The total number of sequence points is 2,500.

OVP /OTP Protection Function

In terms of protection, GSM-20H10 provides OVP/OTP protection modes; in the design of OVP, users can define the range of OVP, and the protection of OTP can effectively prevent errors caused by temperature drift during the test process.

0.012% Basic Measure Accuracy with 6½-digit Resolution

GSM-20H10 provides a 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.

Variable Sampling Speed

The sampling rate of GSM-20H10 is variable. Therefore, users can choose the sampling rate from 0.01 PLC to 10 PLC according to their needs.

Where NPLC represents the number of power line cycles, for example, AC power frequency is 50Hz, 1 PLC means 20ms, 2 PLC means 40ms, and so on.

Digit Selectable

SDM (Source Delay Measure) Cycle

The initial state of the source output may be unstable. If the meter starts measuring after the source is output, users can set the source delay to start the meter measurement after passing the unstable period so as to obtain stable measurement results.

GSM-20H10 precision source meter’s delay range is 0 to 9999.999 seconds.

2-, 4-, and 6-wire Remote V-source and Measure Sensing

Other than 2-wire, 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 eliminate the effects of internal parallel resistance, realizing the resistance measurement of a tiny wire.

Variable Display Digits

The display bits of GSM-20H10 are variable. Therefore, users can choose the number of display bits among 3.5, 4.5, 5.5, and 6.5 bits according to their needs.

Built-in Limit Function

GSM-20H10 has three built-in Pass/Fail limit line tests, with a total of 11 sets.

Built-in 5 Calculation Functions

GSM-20H10 provides five built-in calculation functions: Power, Offset Compensation Ohms, Voltage Coefficient, Varistor Alpha, and Percent Deviation.

Standard SCPI Command, Provide Interface: RS-232, USBTMC, LAN, GPIB (Optional)

GSM-20H10 provides a complete remote programming control interfaces, including SCPI RS-232, LAN, USBTMC and GPIB (Optional).

4.3" TFT LCD, Digital Number Keypad

With the large 4.3-inch screen, all measurement settings, parameters, and results can be completely displayed on the screen: the digital number keypad provides users with a more friendly input method.
