Arrived in plastic bags. With USB-C cable to charge the 18650 Li-ion cell. A carrying bag with an English user guide and 4mm probes. The IR function is surprisingly sensitive and do recall itself when necessary. The Macro-lense is useful at up to 3cm distance for a crisp view, which is blurry without. Can take photos with a time-stamp, to be transferred to a connected computer via the USB-cable. Recommended.

Somewhat poor packaging. Two Transformers damaged, due to they slipped out of the plastic packaging. One with crashed HV coil, the other with crushed ferriter core.

Billig antenn omkopplare. Borde ha bestyckats med dubbelbranchig omkopplare, som då gjort att enheten skulle klara > 50 Watts effekt mot dikterade 10 watt. Skärmväggar med elektrisk bra kontakt till chassiet=jordplanet. HF-egenskaper får mätas senare.

bjorwal Oh yes, but for only some 10 to 20 watts. Could be higher attenuation of u connected port by connecting it to a 50ohm load or to ground it. But then it should cost much more...

Q: are these cable/brand certified from apple? cant find them in apple website

Asked by koullis on 2024-02-13 05:17:35

bjorwal Why do you need certification from Apple for just a functional high quality cable accessory ? Certification cost you extra $, but the cable is perhaps better than the expensive ones from Apple...

Turn selector first to the intended range and probes to the suitable recepticals. Then connect the probes. Using 2 AAA NiMH as power source makes the "low battery" symbol visable. Delivered with an English user guide. Warning: The probes are NOT the oedinary 4mm type, they are 3.3mm. Battery check 12V=14mA, 9V=12mA, 3V=12mA and 1.5V=11mA.

Just the right antenna. For tracking EMC non compliance units, these band-shifting antennas are small and useful. Thank you.

Tested about all functions and all turned out to be working OK. Included obviously an EMI filter, and noise output is low. Cooling fan activated when necessary. Short beep when control is not active anymore. USB fast charging mode detected. Happy with this purchase. Thank You.

In comparison with TinySAultra quite a few improvements BUT the menu tree is still not in line with logical and most common usage. An HP -analyzer menu tree is excellent for productivity and use, they have had >50 years of making the tree most productive. When will this unit and TinySAultra have the same structure ? The battery last a few hours of use =excellent. Upper freq of 12GHz or 16 GHz in some settings is superb. Awaiting a F/W update.. Recommended!
