CONTROL COMMAND
• Scope waveform data
Command: 27 00
Outputs the waveform data to the controller
X XX XX X X XX XX X X X ...... X X
q w e r t y u
q Main or Sub scope data
• 00=Main scope, 01=Sub scope
w Order of division data (Current)
e Division number (01 or 15)
When data is sent to the controller through the
LAN port, all data is sent together. However, when
the data is sent through the USB port, the data is
divided by 15 and sent in sequential order.
Division number Data length
LAN 1 704
USB 15
1st data 15
2nd or
later data
53
15th data 42
The 1st data sends only the wave information (q ~
y) without the waveform data (u).
The 2nd or later data sends the minimum wave
information (q ~ e) with waveform data (u).
r Center or Fixed mode data
• 00 = Center mode scope, 01 = Fixed mode scope
t Waveform information
The waveform information is different between
Center mode and fixed mode.
In the Center mode: Center frequency and span are
sent
See page 18-11 for Frequency data, and the Scope
span settings to the right.
• In the Fixed mode: Lower edge and higher edge fre-
quencies are sent
See page 18-16 for Scope Fixed edge frequency set-
tings e ~ !2.
y Out of range information
• 00 = In range, 01 = Out of range
If the scope data is out of range, the waveform
data (u) is omitted.
u 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 basi-
cally the same as the display size of the scope on
the controller.)
Data range 0 ~ 136
Data length 689
