2 Remote Control
2.1 Remote control basis
14
When the value without an indicator is entered, the equipment will ensure that it is entered in decimal
format. The identifiers required in all formats are listed as follows:

#B indicates that this digit is a binary value.

#H indicates that this digit is a hexadecimal value.

#Q indicates an octal number.
The representations of the decimal value 45 in the SCPI are given as follows:
#B101101
#H2D
#Q55
The following example shows setting of the RF output power as 10 dBm (or the value equivalent to the
current selected unit including DBUV or DBUVEMF) with the hexadecimal value 000A.
:POW #H000A
In a non-
decimal format, the measurement unit such as DBM or mV isn‘t used together with the value.
7) Command line structure
A command line may contain multiple SCPIs. To indicate the end of the current command line, the
following methods can be used:

Enter;

Enter and EOI;

EOI and the last data byte.
Commands in command line are separated by semicolons, and commands for different subsystems
begin with a colon. For example:
MEM:COPY:NAME Test1, MeasurementXY;FREQ:CW 5GHz.
This command line contains two commands, in which the first one belongs to the MEM subsystem and
the second one belongs to the FREQ subsystem. If the adjacent commands belong to the same
subsystem, the command path will be partially repeated and the command can be abbreviated. For
example: For example:
FREQ:CW 5GHZ;FREQ:OFFSet 3GHz
This command line contains two commands, both of which belong to the FREQ subsystem and have the
same level. Therefore, the second command can begin with the subordinate to FREQ and may not begin
with a colon, which can be abbreviated to the following command line:
FREQ:CW 5GHz;OFFS 3GHz
8) Unit Description
The programmable commands provided herein support the frequency units Hz, kHz, MHz and GHz. The
programmable commands related to the frequency support parameters without unit, and if the frequency
unit is not provided, the default unit is Hz; the power unit dBm is supported currently, and if the
parameter unit is not provided, the default unit is dBm; the gain and attenuation unit dB is supported, and
if the parameter unit is not provided, the default unit is dB; the time units ns, us, ms and s are supported,
and if the parameter unit is not provided, the default unit is s. See the range of parameters in each
command for the unit type of programmable command parameters provided herein.
