JRE STA-1 overview
I do not start leak finding with an expensive and complex lab spectrum-analyzer setup. The STA-1 arrives configured for enclosure isolation work, so the operator can switch it on and scan the closed setup with the included directional antenna. It can use a suitable existing 2.45 GHz signal or the matched HPSS-1 source.
- Factory-set 2.45 GHz center frequency matching the JRE HPSS-1 source
- Fixed 2 MHz span with nothing to tune for the intended measurement
- 115 dB on-screen dynamic range for comparing open and enclosed readings
- −115 dBm sensitivity for locating weak leakage around the setup
- Directional Yagi antenna included for pinpointing areas of concern
- Rechargeable battery power for portable, cable-free measurements
- 4.5" H x 3" W x 1" D (115 x 75 x 25 mm) handheld body
The analyzer is $585.00. Its fixed configuration is the point: operators are not left to reinterpret frequency, span, and sensitivity settings between checks. Rechargeable battery power keeps the measurement portable and cable-free.
