Giga-tronics Model 8003 Precision Scalar Analyzer combines a 90 dB wide dynamic range with the accuracy and linearity of a power meter in a single instrument.
The Model 8003 Precision Scalar Analyzer can make accurate, single sensor power measurements over a frequency range of 10 MHz to 40 GHz with a dynamic range of -70 to +20 dBm.
This wide dynamic range results from our unique use of switched linear gain stages, with a maximum gain of more than 100 dB, rather than the log amplifiers typically used in scaler analyzers.
In addition to wide dynamic range, our approach also delivers extremely accurate low level measurements all the way down to -70 dBm
The Model 8803 also incorporates a unique built-in power sweep calibrator that linearizes the sensor's diode response in the non-square-law region, from -30 to +20 dBm. The calibration system uses the inherent linearity and stability of an ovenized thermistor to accurately calibrate the high-speed diode sensors from 0 to 50°C, ambient.
The result is a linearity specification of ±0.02 dB (0.5%) over any 20 dB span and ±0.04 dB (1%) over the entire 90 dB dynamic range to ensure accurate ratio or relative measurements.
The same built-in calibrator that linearizes the sensor provides a 1 mW signal accurate to within ±0.7%, stable over temperature and time, and traceable to NIST.
And each Giga-tronics power sensor contains an EEPROM programmed with the frequency calibration factors measured at the factory, or in your cal lab. When you key in the frequency at which power is being measured, the meter automatically applies the correct cal factor from the sensor EEPROM.
The combination of an accurate, traceable calibration reference and an accurate frequency response curve for each power sensor ensures absolute power measurements with power meter accuracy.
Giga-tronics offers an extensive line of power sensors for the Model 8003 to address a variety of power measurement applications. This includes standard CW power sensors, low VSWR CW power sensors, true RMS sensors, and our unique triggerable pulse sensors.
The 80340 Series trigger-able pulse sensors let you display the response from a pulsed source. You can choose between two modes of operation - measure with either a pulsed fixed frequency (CW mode), or with a pulsed swept frequency (start/stop mode) signal from a sweeper. The sensors can also be used to display the response of devices with no pulse modulation on the signal generator.
