discrete spurious signals in the channel, the channel power measurement method
must be used to obtain correct measurement results.
Measurement Example – Measuring the Intrinsic Noise of the R&S
ESRP at 1
GHz in a 1.23 MHz Channel Bandwidth with the Channel Power Function
Test setup:
► Leave the RF input of the R&S
ESRP open-circuited or terminate it with 50 Ω.
Procedure:
1. Set the R&S
ESRP to its default state by pressing the [PRESET] key.
The R&S
ESRP is in its default state.
2. Set the center frequency to
1 GHz
and the span to
1 MHz
.
3. To obtain maximum sensitivity, set RF attenuation on the R&S
ESRP to
0 dB
.
4. Set the "Sweep Type" to "Sweep".
5. Switch on and configure the channel power measurement.
a) Press the [MEAS] key.
b) Press the "Ch Power/ACLR" softkey.
The R&S
ESRP activates the channel or adjacent channel power measurement
according to the currently set configuration.
c) Press the "CP/ACLR Settings" softkey.
d) Press the "Channel Settings" softkey.
e) Press the "Channel Bandwidth" softkey and enter
1.23 MHz
.
The R&S
ESRP displays the 1.23 MHz channel as two vertical lines which are
symmetrical to the center frequency.
