This performance verication test must be performed with the EMC analyzer set
in the spectrum analyzer mode.
This test measures the accuracy of the EMC analyzer CAL OUT signal. The rst
part of the test characterizes the insertion loss of a Low P ass Filter (LPF) and 10
dB Attenuator . The harmonics of the CAL OUT signal are suppressed with the
LPF before the amplitude accuracy is measured using a power meter .
Calibrator Frequency is not included in this procedure because it is a function
of the Frequency Reference (CAL OUT Frequency = 300 MHz 6 [300 MHz 2
Frequency Reference]). P erform the Frequency Reference A ccuracy test to
verify the CAL OUT frequency .
Equipment Required
Synthesized sweeper
Measuring receiver (used as a power meter)
P ower meter
P ower sensor , low power with a 50 MHz reference attenuator
P ower sensor , 100 kHz to 1800 MHz
P ower splitter
10 dB Attenuator , Type N (m to f), dc-12.4 GHz
Filter , low pass (300 MHz)
Cable , Type N, 152 cm (60 in)
A dapter , APC 3.5 (f) to Type N (f)
A dapter , Type N (f) to BNC (m) (two required)
A dapter , Type N (m) to BNC (f)
Procedure
This performance verication test consists of two parts:
P art 1: LPF , Attenuator and A dapter Insertion Loss Characterization
P art 2: Calibrator Amplitude A ccuracy
P erform \P art 1: LPF , Attenuator and A dapter Insertion Loss Characterization"
before \P art 2: Calibrator Amplitude A ccuracy ."
A worksheet is provided at the end of this procedure for calculating the
corrected insertion loss and the calibrator amplitude accuracy .
