Controls and indicators
Power on Switch
This is located on the side of the Comb Generator, and is for powering the Comb Generator on and off. The RF
output of the generator is active whenever the generator is on, except during a low battery condition.
Output connector
The comb generator output is available at the BNC connector located on the top of the unit. This output can be
used for radiated or conducted emissions testing. For radiated measurements, the monopole antenna is attached
to this connector. There are two antennas with BNC male connectors provided to cover the Comb Generator
radiated frequency range. Please refer to page 3 to determine the approximate frequency range of each antenna.
The antenna can be disconnected for conducted emissions measurements. Do not connect the Comb Generator
output to a Line Impedance Stabilization Network (LISN) that is connected to AC power. We also do not
recommend connecting the Comb Generator output directly to a preamplifier input.
Frequency selection switch ( 1 / 5 MHz)
This switch is only available on the model CGO-515. It allows the user to select between 1 or 5 MHz frequency step
size.
Power On indicator
The green power on LED is lit, the Comb Generator is powered on and output is available for measurement.
Battery Low indicator
When the red 'battery low' LED is lit, the internal battery needs recharging. The output may not be reliable. Turn
off Comb Generator and charge the battery with the supplied adapter. The approximate time to fully charge the
battery is 8 hours. The Comb Generator can operate approximately 18 hours when fully charged. Please note
however, that the operating time given in this manual is approximate and depends on the condition of battery,
storage period and the number times it has been charged and discharged. If the operating time keeps decreasing,
you may need to replace the battery pack.
