3-12 Operating Arithmetic Functions
Using dBm Modifier
!
The dBm measurement is used for decibel conversion of power per 1mW
consumption into a 600 load and can be applied to Vdc and Vac
measurement functions only. Voltage measurement is converted to dBm by
using the following formula:
2
dBm = 10x log
[1000 x (measurement value)
/reference impedance]
10
then
to toggle in (and out) dBm modifier mode when measuring
Vdc or Vac function with default reference impedance 600 .
The meter will displays the dBm modifier on the primary display and
displays the reference impedance on the secondary display.
User may then use
and
to rotate the selection of different
impedance as desired when the selection mode is enabled, the reference
impedance selection is shown on the secondary display area.
