How about using a mobile calibration lab? No shipping damage. 1 day turnaround.
A calibration lab I know and trust ranks higher in my book than a lab with a laundry list of accreditations but acts like you are at their mercy. I need more from a calibration lab than a sticker on the front. Years ago I sent my receiver to the manufacturer for Calibration and paid extra money to get onto their “Head of the Line” list. Four weeks and 12 phone calls later, it finally made it to the bench where the technician said there was something wrong with my receiver and it had to be sent to the Repair lab which was at a different location. Four more weeks later, the repair technician called me and said he couldn’t find anything wrong with the receiver, but, their repair lab was not accredited to do calibrations, soooooooooooo, it had to be shipped back to the Calibration lab where this time it was calibrated and shipped back to me with no explanation. Our total down time was 10 weeks. I wonder how long it would have taken if I didn’t pay the extra money to be at the Head of the Line? Oh, my receiver also came back all beat up. The paint on the sides was all worn off from shipping wear. So, that was the last time I sent my receiver to the manufacturer for calibration. Just one of many many calibration horror stories. I currently have a great relationship with my calibration lab. I’m on a first name bases which I would not have it any other way. Your calibration lab has to be someone you trust is doing it right and will be able to properly repair it if necessary. Any time I look to buy a new piece of test equipment, I contact my Calibration Lab (who also does repair on most manufacturers’ equipment) and get their recommendation on make and model. They see what brands and models of equipment have high fallout in function and calibration.

The reasons are probably financial – they haven’t wanted to spend the $ to attain accreditation. We send our R&S receivers out for cal to a well-known accredited cal lab in the US, but we have had an instance of damage by the shipping agent. Jim __________________________ James L.

Does anyone recommend a certain model? I would want one that has at least a frequency range from 150kHz to 18GHz so one unit can be used for radiated and conducted emission measurements. I'm looking for a unit that can be calibrated by a local accredited calibration lab. I believe all R&S receivers need to be sent to them for calibration, which there would be risk and time involved in shipping. Thanks, Tim Pierce ________________________________ One site has it all.
