| Jun 28, 2012 at 16:16 | comment | added | The Photon | OK, but is your oscillator buffered or not? What is the drive capability of the buffer? The answer to your question "will it be able to drive the low impedance...?" depends entirely on details that will only be found in the datasheet(s). | |
| Jun 28, 2012 at 16:15 | comment | added | Joel B | @ThePhoton - 2. I didn't say I expect external components to affect the measurement. For extra components I said I didn't want to "take them into account" which seemed like a nicely ambiguous way to say "There could be frequency effects (which are probably negligible)" but also accomplishes my real intent that "There's a complete circuit for this and there's a minimal solution which will get me decent-enough results for evaluation, I want the latter". Thus saving this question from a trip to meta or the wrath of Olin. | |
| Jun 28, 2012 at 16:11 | comment | added | Joel B | @ThePhoton - 1.I knew someone would ask, but I tried to keep it general since I'll be testing multiple oscillators. I'm hoping to avoid the "here's your circuit for this specific part" solution. | |
| Jun 28, 2012 at 15:42 | comment | added | The Photon | 1. A datasheet for your oscillator would help us answer your question. 2. If you're just measuring frequency accuracy, why would you expect external filters to affect the measurment? 3. If you expect an external filter to affect the measurment, why don't you expect a drastic change in the load to affect the measurement? | |
