Zero Long Code Mask
By default the zero long code mask is enabled so that a long code mask consisting of
all zeros is used. Thus the data transmitted on the forward (and reverse) link is
unscrambled. This is needful that a mobile station could synchronize to the signal.
This parameter is dimmed and not editable.
ON : A long code mask consisting of all zeros is used.
6.3.5 Power Control
This section defines the Power Control Bits (PCB) sequence that the generator trans-
mits via forward traffic sub channel F-FCH to the mobile station to control its total out-
put power.
Power Control Bits
Defines which type of power control bits (PCB) are transmitted from the R&S CMW (via
F-FCH) to the MS. The PCB controls the MS total output power.
●
OFF : Disables the puncture of power control bits onto the signal of the F-FCH.
●
All Up : Punctures only
0
as power control bits.
●
All Down : Punctures only
1
as power control bits.
●
Hold : Transmits alternating
0
/
1
power control bits. Can be used to keep the current
MS power level constant.

6.4 Programming
The following sections provide programming examples for the CDMA2000 generator
application.
The examples contain SCPI commands supported by the R&S CMW and the following
symbolic scripting commands:
●
// <comment>
:
Adds a <comment> to the protocol generated during execution of the example.
●
WHILE <query> <> <value>
:
Waits until the <query> returns a certain <value>, e.g. a specific state is reached.
●
WAITKEY <message>
:
Displays a dialog box with a <message> and wait until the box is closed by the
user.
