What instruments can be repaired

Oscilloscopes, spectrum analyzers, signal generators, digital multimeters (DMMs), DC/AC power supplies, LCR meters, frequency counters, and temperature, pressure and force measuring instruments used in industry.

FAQ

Does a faulty Keysight instrument have to be sent abroad?

Not necessarily. Techmaster supports the official Keysight RMA/repair process in Vietnam; only special cases are forwarded to the regional service center.

Is re-calibration required after repair?

Yes. Repair can change an instrument’s measuring characteristics, so ISO/IEC 17025 calibration is needed to confirm accuracy before returning it to service.
