Setting the Channel or Frequency Step
You can set the channel or frequency step so you can quickly increment to the next
channel or frequency using the up and down arrow buttons.
Setting the Scrambling Codes
The E7495A/B has two ways to identify the scrambling code being used by the
transmitter under analysis: an automatic detection mode,
Auto, and a
manually-specified mode,
Manual.
•In
Auto mode, the test set automatically detects the scrambling code present in
the signal.
•In
Manual mode, the scrambling code can be entered by you instead of being
auto-detected by the instrument.
If the scrambling code is known, its value can be entered and the test set can decode
and display the code domain power of the signal, even if no P-SCH and S-SCH are
present (a CPICH must be present, however). In normal operating conditions, these
synchronization channels are available, so the P-SCH and S-SCH are used by the
E7495A/B (and W-CDMA or W-CDMA (with HSDPA) mobiles) to determine the
