How to Select Effective Isotropic Radiated Power (EIRP)
—Press Measure 1
—Then Channel Measurements > More > EIRP to open a menu of softkeys to
set up EIRP.
When EIRP is selected, the following settings are available / maintained from a
previous measurement: ???.
How to Setup EIRP (Effective Isotropic Radiated Power)
General setup and an example for EIRP:
For this example we are using an isotropic antenna with the following
specifications:
— Frequency range: 9 kHz to 9 GHz isotropic antenna
— Preamp stages: 2 (+15 dB each (@2 GHz)
— Chop/Switch speed rate: 1 Hz to 50 kHz
— Assume: 600 Series 50
ꭥ coaxial cable with 2.5 dB/100 feet
1. Press Measure 1
> Channel Measurements > Channel Power > More >
EIRP
then choose from the following:
— EIRP Meas
– Enables and disables the EIRP measurement.
— Rx Ant Gain
– Enter the receiver ant gain (–100 db to 100 db;
default = 0 dB).
For this example: 30 dB > Enter.
— Dist to Ant
– Enter the distance between the receiving and
transmitting antennas (0 m to 25 km; default = 100m)
For this example: 100m (default)
— Rx Cable Loss
– Enter the receiver cable loss (0 to –100 dB; default
= 0 dB).
For this example: 2.5 dB
— Margin Comp
– Enter the margin compensation to remove known
self-interference, antenna efficiency, fading and other errors
(–100 db to 100 db; default = 0 dB).
— Then More
