7-24 Remote control
SSFDS In addition to the SSFD command, the ER9000 has the SSFDS instruction.
This command accepts the frequency step parameter (step > 0).
When using, instead, the SSFD command, the ER9000 choses, automatically, the
best step for the RBW in use, as an optimization. In that case, the true step is sent by
the receiver at the beginning of the sweep data.
The syntax is the same as per the SSFD command.
Example:
#SSFDS 9e3;150e3;50;SPQ;2000;26;10;OFF;ON;100;1*
SSSW
This setting command actuates some generic settings for the Sweep Mode.
#SSSW PLM;TGS;TGT;TGF*
Arguments are as follows:
•
PLM
= Pulse Limiter which can be either
On
or
OFF
.
•
TGS = Built-In Generator which can be either On or OFF .
•
TGT = Built-In Generator tracking mode which can be only OFF in Sweep
mode.
•
TGF = tuning frequency for the Built-In Generator when is not tracking
(STGT OFF). The string can be in exponential form and should be
expressed in Hz. Frequency should range between 10 Hz and 30 MHz
inclusive.
Example:
#SSSW ON;OFF;OFF;0* which activates the Pulse Limiter and switches
off all of the internal generators.
SSTP
This setting command stops abruptly a running sweep in Analyzer mode. The reply is
always
STP=OK, which acknowledges the command has been granted
STAT b This setting command sets MinAtt to the value indicated by (b) which range from 0dB
to the maximum available attenuation
and must be in step of 5dB. The reply is
TAT=OK which acknowledges the command has been granted or TAT=SERR if the
command has been ignored.
Note: In Sweep mode the Attenuator is always forced to AUTO
Example:
#STAT 10*
STGF f
This setting command sets the tuning frequency for the Built-In CW signal generator
when it is not tracking (STGT OFF
) . The string (f) can be in exponential form and
should be expressed in Hz.
Frequency should range between 10 Hz and 30 MHz inclusive.
The reply is
TGF=OK which acknowledges the command has been granted or
TGF=SERR if the command has been ignored.
Example:
#STGF 150e3* Sets the tuning frequency, for Built-In CW generator, to
150 kHz.
