KEITHLEY 238 is a high-accuracy electronic test instrument designed to measure current, voltage, and resistance with extreme precision and accuracy. It features a full-range of parameters and is capable of performing a wide variety of basic and complex measurements. With its advanced design, 238 is a versatile tool used to monitor DC power supplies, measure current and voltage, measure resistance, and generate test signals. The primary feature of KEITHLEY 238 is its powerful current/ voltage measurement capabilities. It has a high-speed, 5,000 count, 5-digit, 20 MHz bandwidth current-sensitive voltmeter that can measure direct current (DC) with precision resolution down to 0.001 mA. 238 also has a programmable current range, allowing it to measure both low current and high current sources. The instrument also has a protected variable-voltage output at up to 20 volts peak. This makes it ideal for testing and calibrating DC power supplies, providing accurate results for a variety of low-current circuit components. KEITHLEY 238 includes a highly sensitive voltage measurement system. It records voltage with 6-digit resolution down to 1 microvolt. With programmable AC/DC coupling and variable gain, it can accurately measure any voltage source, from DC to HF frequencies. The high-speed voltage measurements are possible through a low-noise and low-distortion high-impedance input, making 238 an invaluable tool for measuring and troubleshooting power-supply accuracy. KEITHLEY 238 also has advanced resistance measurement capabilities. It is equipped with a four-wire, 6-digit/10-digit resistance measurement system with a resolution down to 0.1 micro-ohms. High-resolution measurements also include precise 4- and 6-digit resistance measurements with 10nA current source and 0.01 micro-ohm resolution. These features make 238 an ideal tool for measuring and evaluating resistance in both low- and high-impedance circuits. The instrument also features a variable frequency generator that can produce signals in the range of 10 Hz to 200 kHz. This makes KEITHLEY 238 the perfect tool for testing frequency response, harmonic distortion, and waveform generation. All these features make 238 an indispensable tool for electrical and electronic engineers for measuring power supplies, analyzing circuit performance, and evaluating circuit components. With its precise calibration and accurate measurement capabilities, KEITHLEY 238 is a high-accuracy solution for a variety of test and measurement needs.
