Emission Reference Source

Emission Reference Source -- ERS

See ERS on the cover of the 1999 ITEM Issue!

Calibrate your test site with precision Emission Reference Source.

Emission Reference Source (ERS) is a portable self-contained RF comb generator that produces waveforms from 30MHz to 1GHz in 2MHz steps. ERS has top-loaded broadband monopole antenna allowing vertical and horizontal polarization test.

ESR is calibrated at National Physics Laboratory in U.K. (equivalent of U.S.' NIST) at the "ideal" test site at 3m distance. ERS is well suited for providing reference between different test sites and for periodic calibration of a well-kept test site.

ERS is also a part of Laplace EMC Test System where it is used for neutralizing effect of reflections at the non-ideal test site.

Features

Frequency:

 

The usable output power covers the range required for radiated EMC work,
ie 30MHz to 1GHz. The actual output in fact extends down to 2MHz for low
frequency work.

Antenna:

 

Included antenna is a top loaded monopole, which is detachable for storage.

Polarity:

 

The ERS can be operated on its base to give vertical polarized output or on
its side to give horizontal polarization.

Direct:

 

An output is provided via a BNC connector to enable direct connection for testing
of cables and filters.

Signal type:

 

The output signal is a harmonic series with a fundamental of 2MHz giving effective
energy at all frequencies in the specified range.

Power:

 

The supplied batteries are rechargeable and a separate AC charger is included
with the ERS.

Power protection:

 

The internal control circuits include a battery-monitoring feature that automatically
switches the ERS down to a standby mode with the OK indicator off if the batteries
become too low for correct operation. This avoids the battery going into deep discharge.
