The Syntax of Program Messages
Parameters
One
<space>
has to be inserted between the command character string of the
subsystem and the first parameter.
When more than one parameter has to be added to a command, commas are used
to separate the parameters.
Types of Parameters
Command parameters have many formats. Previously defined fixed formats that
correspond to each command are used in the replies. The formats that may be
used for each command are noted in the command reference.
•
The use of one of the following numeric formats is indicated by <
numeric
>.
100

−
7.89E
−
01
exponential expression with an E or an e
.5
only to the right of the decimal point
There is a limit to the numeric formats that can be used when using a program to
specify the settings of the PCS Interface. A “rounding-off” operation is automatically
carried out if a specified parameter exceeds this limit. <
numeric
> data that is in
response to a Query command is always in an <NR1> (integer) or an <NR3> (decimal
point) format.

Suffixes
When a suffix has to be used with a command, multiplier suffixes (such as
K
for kilo)
and unit suffixes can be used. (If a multiplier suffix is used, it must be accompanied by
a unit suffix, such as HZ.)
Frequency:
HZ
(Hz; default setting),
KHZ
(kHz),
MAHZ
or
MHZ
(MHz),
GHZ
(GHz)
Power:
DBM
(dBm; default setting),
W
(W)
Temperature:
DEG
(°C; default setting)
Suffixes may be omitted. If they are, the default suffixes will be used.
