Create a new text file, and open it with a text editor.
Write the frequency and compensation data in the following format.
* Format
“frequency”: ”compensation data”, “frequency”: “compensation data”, · · ·
Example of M405
300M:0.0DBI,350M:1.0DBI,400M:1.4DBI,450M:1.4DBI,500M:0.0DBI
* Write the unit with a capital letter as it is case sensitive. G (GHz) is also available.
2. Write the text file into the unit with 2650A PC software.
Connect the personal computer to 2650A series with the included USB cable and turn on the power of
the 2650A/2651 series.
From the upper menu of the PC software,
select [File]
→ [Write E/F User Data] in case of electric field strength measurement, or
select [File]
→ [Write M/F User Data] in case of magnetic field strength measurement.
When the text file created beforehand is selected, the data is written.
* Install the specified USB driver in the personal computer prior to using the PC software.
(Refer to “25.3 Installation of Driver”)
4) Method of using original program for writing
1. Prepare the USB communication software.
Connect the personal computer to the 2650A/2651 series with the included USB cable and turn on the
power of the 2650A/2651 series.
2. Write the data into the unit.
Transfer the data in the following format with the USB communication software.
* Format
In case of electric field strength measurement;
EFUSER “frequency”: ”compensation data”, “frequency”: “compensation data”, · · ·
In case of magnetic field strength measurement;
MFUSER “frequency”: ”compensation data”, “frequency”: “compensation data”, · · ·
Example of CP-2S
MFUSER10M:86.7DB,100M:69.2DB,1G:50.7DB,2G:44.9DB,3G:40.1DB
* Write the unit with a capital letter as it is case sensitive. G (GHz) is also available.
3. When the writing ends correctly, “OK” is returned.
5) How to use
Set the measuring function of the 2650A/2651 series to electric field strength measurement mode or
magnetic field strength measurement mode.
By pushing [MEAS]
→ [E/F ANT], electric field strength measurement mode is set.
By pushing [MEAS]
→ [M/F PROBE], magnetic field strength measurement mode is set.
Select “USER” from antennas or probes on the display by pushing [F1].
Then, the measurement by the written data will begin.
* The written data remains even if power is turned off.
* The measuring mode returns to a usual measurement mode when turning off power.
