Produces a ‘pair’ of data values comprising of frequency and its level at MHz order which is defined
(sandwiched) by / /. In reality, there may be a discrepancy of +/- 1dBm between the value of the
marker on the LCD and the level of the same marker which is calculated by this command.
Command : RICD Function : CURSOR DOWNLOAD Command category: READ
Parameter : N/A
Example : RICD Response: 
see remarksRemarks: Read output level of the cursor frequency.
(Example):
========== Start from here ============
f10.70000, l-78CR>
========== End =====================
Note: Use small F or L (not a capital) for this command. This produces the information in one line
unlike the download plot information. In reality, there may be a discrepancy of +/- 1dBm between the
value of the marker on the LCD and the level of the same marker which is calculated by this
command.
Command : RIFD Function : HIGH SPEED DATA DOWNLOAD Command category: READ

========== Start from here ============
IFD
CR>
(Some lines omitted, these are level data area.) #%$-+#!
(Some lines omitted) 


========== End =====================
The level data per frequency will be presented in ASCII code which has been obtained by calculation
of the label, 100 + 0x20.
Note: Use small F or L (not a capital) for this command. In reality, there may be a discrepancy of +/-
1dBm between the value of the marker on the LCD and the level of the same marker which is
calculated by this command.
Command : RIVE Function : READ FIRMWARE VERSION Command category: READ
Parameter : N/A
Example : RIVE Response:

Notes for programmers
Generally speaking the screen dump is preferable if graphic info (data) is
wanted. On the other hand the array of frequency / level can better serve if
numerical data is demanded. The array of frequency / level is faster in transfer
time from the SDU5600 to the PC.
The SDU5600 accepts commands either from the PC or from its own front
panel on a first come first serve basis. For example the PC has sent data to
switch the SPAN bandwidth to 10MHz followed by data from the front panel
setting the same parameter to 5MHz. The SDU5600 will perform the change to
10MHz then to 5MHz.
AOR is considering commissioning a PC control package for the SDU5600,
