: Order of division data (Current): 01~11
3
: Division number (Maximum): 11(USB)
L
When sent through theUSB port, the data is
divided by 11 and sent in sequential order.
L
The 1st data sends only the wave information
(
1
~
6
) without the waveform data (
7
). The
2nd or later data sends the minimum wave
information (
1
~
3
) with waveform data (
7
).
4
: Spectrum scope mode data:
• 00 = Center mode scope
• 01 = Fixed mode scope
• 02 = SCROLL-C mode scope
• 03 = SCROLL-F mode scope
5
: Waveform information:
The waveform information differs, depending on
the Spectrum scope mode.
• In the Center mode:
Center frequency and span are sent.
See page 19-9 of the IC-7300 FULL MANUAL
for Operating frequency data, and the Scope
span settings (
2
~
6
) to the right.
• In the Fixed, SCROLL-C, and SCROLL-F modes:
Lower edge and higher edge frequencies are
sent.

6
: Out of range information:
• 00 = In range
• 01 = Out of range
L
If the scope data is out of range, the waveform
data (
7
) is omitted.
7
: Waveform data:
The transceiver outputs the drawn waveform data.
The data range or data length of the waveform
data is judged by the controller. (The data range
is basically the same as the display size of the
scope on the controller.)
• Data range: 0 ~ 160
• Data length: 475
