Universal Spherical Dipole Source (USDS)

Highly stable comb generator completely contained in a 10 cm (4 inch) spherical dipole enclosure. Comb frequencies include 10 MHz, 64 MHz, 100 MHz, & 133 MHz with the highest operating comb frequency above 16 GHz! A unique feature allows the comb signal to be pulsed on/off to allow testing of quasi-peak detectors! The pulsed mode works for any comb frequency selected.


The frequency range, battery life and usability have all been improved.

The USDS is the most accurate and reliable E-field source for fast measurements available on the market!

Highlights include:

✔Frequency range extended to over 16 GHz
✔Li-Ion Battery extends continuous operations over 15 hours
✔Hemispheres no longer need to be removed for storage or charging
✔International/universal power source for charging batteries
