Spectrum Analyzer

The main features of the device / system from the digital output of the second instrument frequency power transmitter and digital inputs constitute, both via optical fiber connection. Completely avoid the fading and interference in complex electromagnetic environments transmission links. With motor, inverter, transformer, energy-saving lamps and other electrical products, various test conditions specified accuracy as measured lowest nominal accuracy specifications. According to the voltage and current ranges from 1mV ~ 20kV, 100uA ~ 7000A, variable frequency power transmitter has more than 100 kinds of standard models to choose from, for high voltage, high current measurement, both low-voltage, low current transmitter and supporting the use of external sensors, can also be directly variable frequency power transmitter high voltage, high current is measured directly reduce intermediate links, improve the system measurement accuracy. Each analyzer can be configured from 1 to 6 power unit (frequency power transmitter), the test project more power units, multiple analyzers can be cascaded, in the synchronous optical control, multi-analyzer precise synchronization between measurements.
