This performance verication test must be performed with the EMC analyzer set in the spectrum analyzer mode.
The tracking generator output is connected to the EMC analyzer input and the tracking is adjusted at 300 MHz for a maximum signal level. A calibrated power sensor is then connected to the tracking generator output to measure the power level at 300 MHz. The measuring receiver is set for RATIO mode so that future power level readings are in dB relative to the power level at 300 MHz.
The tracking generator is then stepped to several frequencies throughout its range. The output power dierence relative to the power level at 300 MHz is measured at each frequency and recorded.
For frequencies below 100 kHz, a digital voltmeter and precision 50 ohm termination are used to measure the power of the tracking generator output. The DVM is set to readout in dBm using the MATH function with R value set to
50 ohms. The dBm equation used is :
dBm = 10LOG R
1mW
E2 !
The DVM readout is corrected by making the readings relative to the 100 kHz reading from the power sensor.
