Re: [time-nuts] Owner's Manual and advice for Austron 2110 Disciplined Frequency Standard
Hi Tim; I am a little late to this string, Did you find the information you needed? I do have an Operation and Service Manual in my archive. One thing I have done with these is up grade the LCD to a high contrast LED back lite display. I can send you details on how to do that. My only request is that if I loan the manual, you make a decent quality PDF for one of the T-Nut members to host for future member use. Please contact me directly if I can be of assistance.

This unit reports that it is not warmed up even though the external temperature of the case of the crystal oscillator reaches ~15 C temperature rise in a few hours as expected. The internal oscillator is an Austron Model 1150 (S/N 4423 with frequency outputs of 5 and 10 MHz, P/N 25299983). I believe that this request has been posted before, but a few years ago. Does the oscillator, by not correctly reporting as being warmed up, inhibit other functions? The frequency output, after a few hours, gets within a few parts in 10E-8 on both 5 and 10 MHz. So I have faith the basic frequency generation capability is not trashed, but I can't get many other function to work as expected. Any help would be greatly appreciated for either the 2110 or the 1150 oscillator. Feel free to contact me off list.

Hi It’s probably bringing out both sides of the varicap to accomplish the same sort of thing.

Re: [time-nuts] Owner's Manual and advice for Austron 2110 Disciplined Frequency Standard
Hi The 1150 OCXO has an EFC pin on it. The output *should* tune to both sides of 10 MHz. Since this is an old box, the OCXO may have aged far enough to keep that from happening. If the EFC is railed, it is a good bet you need to tune the OCXO with the mechanical trimmer that is behind the seal screw on the OCXO. If that trimmer is already at limit and you can’t get to 10 MHz …. not a good thing.
