• Scope waveform data

Command: 27 00
Outputs the waveform data to the controller (PC)�

0 0 X X X X X X X X
1: 00 (Fixed)
2: Order of division data (Current): 01~11
3: Division number (Maximum): 01(LAN), 11(USB)
L When data is sent to the controller (PC) using the
[LAN] port, all data is sent together� However, when
the data is sent through the [USB] 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 "00" (1), the order of division data
(Current) (2), the division number (Maximum) (3),
and the 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 16 for Operating frequency data,
and the Scope span settings (2 ~ 6)�
L When the 5600 MHz or lower band is selected, the
Center frequency is 10 digits (5 bytes)�
When the 10 GHz band is selected, the Center
frequency is 12 digits (6 bytes) from 100 GHz to
1 Hz�
• In the Fixed, SCROLL-C, and SCROLL-F modes:
Lower edge and higher edge frequencies are
sent�
See the Scope Fixed edge frequency settings 3
~ 14 on page 29�
L When the Higher Edge or Lower Edge frequency is
in the 10 GHz band, the each Edge frequency is 12
digits (6 bytes) from 100 GHz to 1 Hz�
When the Lower Edge frequency is negative, the
100 GHz digit is set to "F," and the other than 100
GHz digit are set to absolute value of the frequency�

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 (PC)� (The data
range is basically the same as the display size of
the scope on the controller (PC)�)
• Data range: 00 ~ A0 (0 ~ 160)
