Can the Tinysa Ultra's RF output be calibrated in generator mode?

JCR All Messages By This Member #19277 Hello. First of all, congratulations on a great job with the Tinysa ultra. I have the ZS405 version with firmware 1.4-192 and I would like to discuss a topic with you. The frequency accuracy in RF generator mode. I have checked the output at different frequencies and there are errors which are the following: 1MHz +6.5Hz; 10MHz +3.8Hz; 50MHz -8Hz; 100MHz -23Hz; 200MHz -51.4Hz; 300MHz -81Hz; 500MHz -142Hz; 800MHz -242Hz; 1GHz -350Hz; 2GHz -611Hz; 3GHz -900Hz I cannot check beyond 3GHz because the Tinysa ultra does not have enough dBm output for my GPS-referenced frequency counter and the preamplifier I have only reaches up to 3GHz.

The low output frequency can be set with a resolution of about 28Hz so after calibration all frequencies up to 800MHz should be correct within +/- 28Hz.? Can't remember the spec after 800 MHz. ?
