* Please write unit with a capital letter.
3. After writing is completed correctly, “OK” is returned from 2650/2658 .
5) How to use
1. Please set the measuring function of 2650/2658 to electric field strength measurement mode or
magnetic field strength measurement mode.
On the case of electric field strength measurement, please select [MEAS] → [E/F ANT],
on the case of magnetic field strength measurement, please select [MEAS] → [M/F PROBE],
Please push [F1] and display [USER] on the upper of [F1].
Now, electric field strength measurement or magnetic field strength measurement by the written
compensation data can be performed.
* When the power supply of 2650/2658 is turned off at once and turned on again it returns from
electric field strength measurement mode or magnetic field strength measurement mode to the
usual measurement mode. Then if it goes into electric field measurement mode or magnetic
field strength measurement mode once again, it can measure in the same state.
6) About the antenna gain
In this contents, the antenna gain is meaning absolute gain [dBi].
When antenna gain is relative gain, it can change into absolute gain by adding +2.15dB.
· Absolute gain [dBi] = Relative gain [dBd] + 2.15dB
As reference, the conversion formula to electric field strength is using the following.
· E= √ (480 π 2 × Pa ÷ (Ga × λ 2 )
E: Electric field strength [V/m]
Pa: Received electric power [W]
Ga: Antenna gain [times] = 10 (antenna gain [dBi] ÷ 10)
λ : Wavelength [m] = (3 × 10 8 ) ÷ frequency [Hz]
