2-4 Parameter and Data Entry Commands
Table 2-2 on page 2-5 lists the command mnemonic codes that open parameters for data entry. The table also
provides the range of values permitted for each parameter and the data terminator mnemonic codes for each.
Table 2-3 on page 2-10 and Table 2-4 on page 2-10 list the data entry and data terminator command mnemonic
codes.
Opening a Parameter
All of the commands listed in Table 2-2 open a parameter for data entry. Once opened, a parameter remains
open until one of the following occurs:
• Another parameter is opened
• A function other than video markers or output power leveling is commanded
• The
CLO
(close open parameter) command is received
Data Entry
When a parameter is open for data entry, its value can be changed as follows:
• By sending a numeric value followed by the appropriate terminator code
• By incrementing or decrementing its value using an associated step size
The parameter and data entry commands do not affect the signal generator’s output unless the parameter
being changed is also the current output parameter. The commands, therefore, may be used to change the
preset values of parameters without altering the MG369xC's output.
Example: Assume that the MG369xC is executing an F3-F4 sweep from 3 GHz to 10 GHz. Changing the value
of F1 to 3 GHz with the command string “
F1 3 GH
” does not affect the current output of the signal generator.
However, changing the value of F4 with the command string “
F4 16.01 GH
” alters the output of the MG369xC
because it changes the end point of the F3-F4 sweep to 16.01 GHz.
Note
An appropriate data terminator must be used to terminate a numeric-parameter entry, and it must
immediately follow the numeric value. If it does not, a parameter entry error will result. For example,
data terminators do not change the mode of operation from log to linear.
Note
40 MHz pulse clock rates are only available with Option 24; 100 MHz pulse clock rates are only
available with Option 26.
