300 WCDMA Options Version 6.20
:CONFigure:ESYNc
:CONFigure:WCDMa:POWMeasure:RRCFilter
Parameters
string1 is a comment line related to the coupling loss data. The maximum length
of string1 is 255 characters.
realfx are floating point real numbers, giving frequencies in MHz while realax
are floating point real numbers, giving the corresponding coupling loss in dB.
All realfx have to be within two frequency ranges. The lower frequency range is
from 800.0 MHz to 1000.0 MHz; the higher frequency range is from
1700.0 MHz to 2000.0 MHz.
The minimum resolution for all realfx values is 10 Hz (0.00001 MHz).
The default value for all realfx is 800.0 MHz.
The minimum value for all realax is -5.0 dB.
The maximum value for all realax is 40.0 dB.
The minimum resolution for all realax is 0.01 dB.
The default value for all realax is 0.0.
Notes
– Please keep in mind that at least one pair of values for a frequency and the
related attenuation must be specified per frequency range, while all other 18
pairs are optional.
– All realax values are interpreted as an attenuation level in dB. As a conse-
quence, negative values mean an amplification of the input signal.
Description
With the help of this command, you may create a coupling loss description table,
similar to how you would do it on the graphical user interface of the Willtek 4400.
Query
There is no query form of this command available.
Example
:CONFigure:COUPloss:DATA "Motorola 7389 with cable
#23",825.0,15.0,1750.0,19.0
Syntax
:CONFigure:ESYNc?
Parameters
There are no parameters.
Description
There is solely a query form of this command available.
Query
The query form will return the status of the current external synchronization. The
string delivered back will contain one of the following expressions:
NONE|MHZ5|MHZ10|MHZ13.
Example
:CONFigure:ESYNc?
Value returned for example: "MHZ10”.
In this example, the 4400 frequency reference is synchronized to an external 10 MHz
clock signal fed into the EXT SYNC connector on the rear panel.
Syntax
:CONFigure:WCDMa:POWMeasure:RRCFilter <PredefExp>
Parameters
PredefExp is one of the following predefined expressions:
ON|OFF. The default is
ON
.
Description
This command sets the state of the RRC Filter for power measurements.
