R&S FSH
Digital Modulation Analyzer
Measurements on CDMA2000 Signals
Operating Manual 1309.6275.12 - 14

Channel Type
Type of channel. (---) indicates an inactive channel. The following channels can be
detected:
Channel Type
Channel
F-PICH
Pilot channel (displayed as PICH)
F-SYNC
Synchronization channel (displayed as SYNC)
All other channel types are not automatically differentiated and named as “CHAN”.
Walsh Ch.SF
Channel number including the spreading factor (in the form <Channel>.<SF>).
Symb. Rate (ksps)
Symbol rate that the channel is transmitted with (9.6 ksps to 307.2 ksps).
RC
Radio configuration. The RC is a predefined physical layer configuration for the
transmit signal. It defines the physical channel configuration based upon a specific
channel data rate. In the current CDMA2000 Standard nine RCs are defined in the
forward link.
Status
Status display. Unassigned codes are identified as inactive channels.
Power Abs (dBm)
Absolute power of the channel in dBm.
Power Rel to PICH [Total] (dB)
Relative power of the channel in dB. The reference channel is the PICH or the total
signal, depending on the reference power you have selected.
7.3.4 The PN Scanner
If you equip the R&S FSH with option R&S FSH-K46E, the PN scanner becomes
available.
If you are measuring over-the-air (OTA) signals, you can use the PN scanner result
display that shows the PN offset and the corresponding power. In order to be able to
determine the PN offsets of the base station you are scanning, you have to apply a
trigger to the R&S FSH from a GPS device such as the optional GPS receiver.
Note that the PN scanner result display shows the detected base station PN offsets as
well as the relative powers of these base stations. Above the display, the PN offsets
are listed in a table.
