7.5 Command Programming Guide
To write an efficient measurement program, pay attention to the following points:
(1) Initialization
To avoid influence by the previous setting, initialize MT8820A before starting
measurement. Select an initialization level according to the measurement.
(2) Use manual operation procedure as a reference for command transmis-
sion order
Take care of the command sending order when creating a remote control pro-
gram. Command sending order is basically the same as that in the manual op-
eration procedure. Thus understand the operation flow of the program to be
created by manual operation. Especially in case measurement results are read
after measurement, no commands other than query commands should be sent
until all the results are read out.
(3) Pay attention to the command syntax
Avoid interruption of a command caused by a command syntax error. Espe-
cially, pay attention to the presence/absence of a space as well as comma and
parameter setting method.
(4) Pay attention to the response unit.
When reading measurement results during remote control, the response unit is
always returned in pre-specified unit. Note that the response unit differs from
the unit of displayed notation.
(5) To enhance measurement throughput
To enhance measurement throughput, the following methods are available:
• Understand the initial value and change the required parameters only.
• Avoid sending commands not directly related to measurement.
• Make the number of screen switchovers to the minimum.
