JRE HPSS-1 overview
An enclosure specification is useful, but I use a radiated source to verify that the assembled setup is still isolating. The HPSS-1 supplies that known signal from inside the enclosure without running an external power cable across the barrier. Where the lab wants a matched receiver, the STA-1 is the direct pairing.
- Synthesized 2.45 GHz source for stable readings with narrow analyzer bandwidths
- Minimum +23 dBm output, typically +25 to +27 dBm
- High output supports isolation measurements of over 120 dB
- 4 hour runtime from the internal rechargeable battery pack
- SMA Female RF output with a half-wave dipole whip antenna included
- Micro USB charger connection for the self-contained source
- 1.2" H x 4.75" W x 6.5" D rugged aluminum enclosure
Choose the HPSS-1 when the lab already has a spectrum analyzer that can tune to 2.45 GHz. The source is $1,385.00. For periodic checks after shipping or reconfiguration, battery operation keeps the measurement setup from introducing a new cable path.
