Received a Racal 2202R today and after preparing space to accommodate it found it's longer than expected. Doh! I thought it had the same dimensions as the 1998
Oh well, more re-adjustments required.
This is the Rb version and it provides a 10MHz reference output which I will use to sync the 1998, SDG1025, and the Tek scope so they play together nicely. That's the plan anyway. In this photo the gear has been powered up for 30min, the SDG1025 is using its internal reference (an upgraded TCXO).
Edit: Ok, fully warmed up now I should think after 3 hours. The SDG1025 is using the external 10MHz reference provided by the 2202, it is outputting 20MHz back to the 2202 (which reads 20 MHz exactly - hardly surprising), the 1998 reads a little under @ 19.999,999,7MHz (using its internal OCXO), while the cheap Chinese 8-digit counter is reading 20.000,001 MHz (amazingly accurate for an £8 counter).
