Understanding the Reference Measurement Channel
The signal generator provides one-button setup capabilities for transport channel
configuration. The dedicated physical channel DCH (downlink) or DPDCH (uplink) is
predefined by pressing the
Ref Measure Setup softkey (or sending the appropriate SCPI
commands). For downlink, at least one physical channel needs to be set to DPCH to
activate the
Ref Measure Setup softkey. Also, to activate the Config Transport softkey, one of
the reference measurement rates must be selected or the DPCH Data field value must be
set to Transport CH. For uplink,
DPDCH and RMC 12.2 kbps are the default selections,
respectively.
Table 4-12 and Table 4-13 describe the downlink and uplink reference measurement
channel (RMC) configurations generated by pressing the
Ref Measure Setup softkey after
signal generator preset. Transport channel parameters can be modified in a table editor by
pressing the
Config Transport softkey, then moving the cursor to the desired data field and
pressing
Edit Item. DPCH and DPDCH parameters can be individually modified in a table
editor by pressing
PhyCH Setup, then moving the cursor to the desired data field and
pressing
Edit Item.

b. If a transport configuration parameter is changed using the Config Transport
softkey and the table editor, the Data field reverts to Transport CH, showing that it no longer con-
tains a specified reference measurement channel.
