Generator Function Check

As with all testing equipment, the continuous wave simulator type CWS 500N2 should be checked for
performance and accuracy from time to time. The check should be completed as listed below.
- Connect the RF-output of the CWS 500N2 to the 40dB-attenuator or an adequate attenuator.
- Switch on the power supply.
- Select the in Quickstart with the following parameters:
Attenuation : 30dB
Frequency : 23MHz
Modulation : OFF, 2Hz, 400Hz or 1kHz
- Connect the output of the 40dB-attenuator with the 50 input channel of the oscilloscope. Take care to the
rated power of the used attenuators!
ATTENTION
- Push "TEST ON" and start the test.
ATTENTION
Using an oscilloscope or powermeter for checking the
operation of the generator very easy. Fig 5.1.
Take notice that this procedure is only a functional check of
the generator. Differences in the test level may be caused
by a limited bandwidth or mismatching within the testing
system.
Exact and accurate measurements can only be guaranteed
with the specified test setup according to standard.
Expected values 23 dBm
Remark:
- 30dB : Setted attenuation
+ 53dB : Gain of the amplifier
+ 23dB : Measuring result
Take attention to the used attenuator (40dB) for calculate the correct measuring result.
User manual
Take attention to the maximum input power capability and the bandwidth of
the test input and power of the used attenuators.
Using two 20dB attenuators with 15W each
Generator ATT setting range: 10 dB to 63.5 dB will not destroy the attenuators
DO NOT connect the output of the attenuator nor the output of the CWS 500N2
to the monitor input without sufficient attenuation, otherwise the monitor input will
be destroyed.
(-30dB + 53dB = 23dBm  4dB)
