[Flexradio] The GPSDO option in the 6000

2012-05-20 Thread Jerry Flanders
From page 5 of the 6000 brochure: When the GPSDO option is not installed, the FLEX-6700 and FLEX- 6700R come standard with a ±0.02ppm Oven Controlled Crystal Oscillator (OCXO) and the FLEX-6500 comes with at ±0.5ppm Temperature Controlled Crystal Oscillator (TCXO). So if I buy the GPSDO

The GPSDO is a TCXO that is disciplined by a GPS receiver. The radio switches to the GPSDO when it is present. The GPSDO remains on in the radio even when the main power is turned off to maintain the high stability oscillator and the GPS lock (unless overridden by the user). Steve On Sunday,

Read your ad copy - it seems to say that the OXCO is not included when one orders the GPSDO option. Is the OXCO/TCXO included irregardless of the option order? Jerry W4UK At 05:44 PM 5/20/2012, you wrote: The GPSDO is a TCXO that is disciplined by a GPS receiver. The radio switches to the

1. The OCXO or TCXO (depending on your radio, FLEX-6700 or FLEX-6500, respectively) are soldered to the board and do not go away with the GPSDO. They are just not used. 2. Phase noise of the oscillator is not particularly important as it goes through a jitter cleaner. It is a reference, not a

Perhaps we are not asking about the same thing. I've not seen a GPSDO on a single IC. Steve On Sunday, May 20, 2012, Jay Grizzard wrote: On Sun, May 20, 2012 at 07:08:27PM -0500, Stephen Hicks, N5AC wrote: 1. The OCXO or TCXO (depending on your radio, FLEX-6700 or FLEX-6500, respectively)
