Spectrum and Network Analyzer Calibration

Spectrum analyzers and network analyzers are the core instruments of RF work, and both depend on accurate frequency, amplitude, and level measurements. Over time, their internal references drift, components age, and input stages can be damaged by signals beyond their rated level, sometimes without any obvious symptom. An analyzer can display a clean, believable trace while reporting signal levels that are a few dB off.

Calibration verifies the analyzer’s frequency accuracy, amplitude accuracy, and other key specifications across its range, so the measurements behind your design, production, and compliance data are trustworthy.

Signal Generator Calibration

Signal and sweep generators are sources: other instruments and devices are tested against what they put out. If a generator’s output level or frequency is off, every test that uses it inherits the error. Calibration verifies that the frequency and output power your generator reports match what it actually delivers.

RF Power Meter and Sensor Calibration

RF power measurements are only as good as the sensor making them. Power sensors are sensitive to overload, connector wear, and rough handling, and each sensor’s response varies with frequency. Calibrating the meter and its sensors keeps transmitter power, amplifier output, and other power measurements accurate.

Attenuator and Filter Calibration

Attenuators and filters are passive components, but they still change over time. Connectors wear with every mating cycle, and damage or overpowering can shift their characteristics. Calibration measures attenuation, insertion loss, and frequency response, so you know exactly how each component affects the signals passing through it.
