As a power supply I use а charger from vy old GSM Mobile Phone MOTOROLA V50, V3690, V3688, P7389, Timeport T280, CD930,  etc... It is one of the best quality switching power supplies I have ever seen. No one produces such quality chargers these days. I have one running 24h a day, 365 days a year for 7 years and it still works like new.

As a 'load calibration standard' I use the '50 OHM / 18GHz / High Quality / Motorola SMA load', bought from eBay. Not a real calibration standard in fact, but under 1.3GHz it does the job.  'OPEN and SHORT' calibration standards for DG8SAQ VNWA are homemade:

Special attention must be paid to 'the short' in the SHORT calibration standard. I made a disk from silver plated copper with hole for the central pin, then solder it precisely with little solder. Bottom plane of the disc, which makes 'the short' must be clean from solder. Many different constructions of 'the short' can be made, but only few of them will work well at high frequencies, so be careful and take care about asymmetry.

Most often i use another home made cal. standards for calibration at end of the coaxial cables:

It was easy to made it. Design is free from errors in the calibration plane. For load cal. standard i use 2x100 Ohm 1% precise SMD resistors. The same type of SMA-Female (SMA Jack) connectors can be soldered to various DUT.

Finally i put all cal. standards, few adapters, dummy loads and attenuators in this metal RED BOX:

I always have lack of coaxial adapters, so I bought also this beautiful "Universal RF Coaxial Adapter kit" with 40 pcs, (maybe gold plated):

Guess what? Now I am 100% sure that no matter how many adapters you have, they are always NOT enough :)! It would be great, if they work as well, as they look, but at least they work :). The loss of one GOLD adapter is less than -0.03dB at 150MHz and less than -0.09dB at 440MHz. I rate this as 'not very good', knowing that other simple cheap adapters in my shack outperform this specifications 2 to 5 times.

Then it comes - "USB to VNWA Convertor":

VNWA as a kit is not available anymore, but you can buy ready to run device, so you will have more time to work with it, instead of soldering and assembling. Initially this was rated as "easy task" by lot of us, but the yahoo group was filled with questions, even if the entire assembling process was very well documented. Most of the problems was caused by improperly soldered DDS IC's and this was the main reason for the author to stop offering the kit. This step allow him to focusing on the improvements and upgrades, instead of remotely tracing errors in assembly.

To do: "CROSSOVER PORT SWITCHING BOX".
