24.4 Input the frequency
For the items written (
*******
=Refer to [24.4 Input the frequency]) in [25.3 Command description]
above, enter a frequency as follows.
*******
=0.0k to 999.9k[0.1step, unit: Hz]
0.0M to 999.9M[0.1step, unit: Hz]
2650/2652: 0.0000G to 3.3G[0.0001step, unit: Hz]
2658: 0.0000G to 8.5G[0.0001step, unit: Hz]
* However, the offset frequency and zone width can be input only in the range decided by the center
frequency and frequency span. The value out of the range becomes error.
* Values of the offset frequency and the zone width will change as you alter the frequency span.
24.5 Writing of original compensation data
On the case of electric field strength measurement used the antenna prepared by the user, or,
on the case of magnetic field strength measurement used the magnetic field probe prepared by the user,
it is necessary to write the data of the antenna gain or the magnetic probe field compensation coefficient to
2650/2652/2658 main unit. Please write the antenna gain or the magnetic probe field compensation
coefficient according to the following description. There are two kinds of methods, “method 1: use PC
software AK 2650 (optional)” and “method 2: use communication program which is prepared by user”.
1) Preparation things
· RS-232C interface cable
· Windows
®
PC (with RS-232C interface) * It is not writable with 2650/2652/2658 main unit only.
· PC software AK 2650 (case of “Method 1 of writing data”)
2) Write-in data
As example, the compensation data (antenna gain) of antenna AN305 and the compensation data
(compensation coefficient) of magnetic field probe PR 26M are shown below.
· Compensation data (antenna gain) of antenna AN305.
Frequency 300MHz 350MHz 400MHz 450MHz 500MHz
Antenna gain 0.0dBi 1.0dBi 1.4dBi 1.4dBi 0.0dBi
· Compensation data (compensation coefficient) of magnetic field probe PR 26M.
Frequency 10MHz 100MHz 1GHz 2GHz 3GHz
Compensation coefficient 86.7dB 69.2dB 50.7dB 44.9dB 40.1dB
