M
Press the MEAS key.
M
Press the "Display Settings" softkey.
M
Select either the "Hadamard" or the "BitReverse" menu item.
The R&S FSH adjusts the code display accordingly.
7.3.5.3 Changing the Reference Power
The y-axis represents the power of the signal. The power of the codes is relative either
to the total power of the signal or relative to the power of the pilot channel (PICH).
M
Press the MEAS key.
M
Press the "Power Settings" softkey.
M
Select either the "Code Power Relative To Pilot" or "Code Power Relative To Total"
menu item.
By default, the R&S FSH displays the power in the unit dBm.
7.3.5.4 Selecting the Unit of the Carrier Frequency Error
The absolute frequency error is the sum of the frequency error of the R&S FSH and
that of the device under test. If the frequency error is more than 1 kHz, the R&S FSH is
not able to synchronize with the signal. If possible, you should synchronize the receiver
and the transmitter.
The carrier frequency error can have the unit Hz or ppm.
M
Press the MEAS key.
M
Press the "Display Settings" softkey.
M
Select the "Hz" or "ppm" menu item.
The R&S FSH shows the carrier frequency error in the unit you have selected.
