Successive addressing of channels according to the chosen sort

on the channels according to the selected sort order. To do this:
• Use the cursor key to choose the cursor A or B for use on the trace.
• Press the <Channel> key.
• Press on the > or < key to make the cursor jump back to the previous channel
or on to the following channel:
- with the frequency sort, the cursor follows the normal order of channels.
- with the level sort, the cursor follows the order of the channel levels.
- with the SNR sort, the cursor follows the order of S/N ratios.
Table remarks
A remark with the maximum of 40 characters, entered by the user, can be
associated with each channel. For each trace, a maximum of 16 remarks is
possible.
Notes
These remarks appear in the table if they have been validated in the
«OSA test setup» menu on the Remarks in table line ( Display win-

the position of the channels is stored.
