CGE01R: Radiated version with integrated wideband
monopole antenna (as previously available)
CGE01C: With SMA output for direct
connection 
|
Radiated Emissions
Available either with an integral monocone
antenna or with a detachable monocone antenna the CGE01 can be
used as a reference source for radiated emissions. The unit is
battery powered so that it can be operated as an independent
source without the effect of power or interconnecting cables,
which would modify the fields generated. Additionally though,
for making shielding effectiveness measurements of small
enclosures, the actual emitter can be separated from the battery
pack and operated remotely via a cable carrying only DC power.
The CGE is housed in a plated metal cylindrical enclosure, thus
ensuring uniformity of the field and can be orientated to give
vertical or horizontal polarization. Additionally external
antennas can be attached to the output when required.
Conducted Emissions
The CGE01C is supplied with a 50Ω SMA
connector allowing it to be used either for the investigation of
conducted systems or to be used with an external antenna. The
known output allows unknowns within systems or components to be
measured or calculated.

Comb Generator
|
 The DSI Model CG-1800 Comb Generator is an
inexpensive narrowband calibration signal source which is extremely
useful for any application that requires precisely calibrated signal
levels to 18 GHz.
The Comb
Generator outputs a coherent comb from 0.1 GHz to 18 GHz, with a comb
line spacing of 100 MHz and the frequency stability of a
temperature-stabilized crystal oscillator.
The CG-1800
features an uncomplicated front panel with digital displays to indicate
the actual output level in dBuV for any selected comb line. Panel
controls allow selection of RF output amplitude in either a leveled or
unleveled mode. All front panel functions are remotely readable and
programmable via the IEEE-488 bus.
When used in DSI's automated measurement
systems, the CG-1800 provides a source for automatic calibration
checking at a fraction of the price of a comparable CW source.
