This is a very interesting instrument at a moderate price. The RF range from 50 kHz to 4400 MHz is conveniently covered, with better performance as compared to other instruments of similar, or lightly lower price. - The ports are equipped with N connectors, allowing to use a variety of adapters of good quality as N to BNC, or N to SMA, even N to APC7! - The SMA standards (open, short load) are of good qualities, especially the load standard. However, the provided RG316 cables, although of good quality are poor. It could be better to use cables of the RG214 or RG402 types. Secondly, there is a parasitic resonance, appearing on S21, at around 1.5 GHz. This seems to originate in the internal circuit, not due to the connectors, adapters or cables. This is an issue. Finally, I regret that this instrument is unable to give a good response as the impedance (through S21) of a crystal or even crystal filters.This is due, as with other similar instruments, to the manner the frequency is swept. This probably the price to paid to have a fast sweeping. However, it may be possible to get a good response (although in a slower time) using some sweeping algorithm, may be as an option if the firmware. Nevertheless, this instrument is funny to use, the interface is well constructed without unnecessary "gadgets". At all a recommended instruments for the amateur and for some professional.
