just another word: It's interestig to plot the phase response by means of a PLL. In this technique the quartz is used as a Phase shifter whose phase depend upon frequency. Sending into the quartz a smal sinewave at different frequency by varying the PLL programmed freq and analyzing the...
Re: Transistor Model
So much models are unuseful in my opinion: every manufacturer gives two or three models (linear or nonlinear) bu nobody gives the RMS error of theese models. Tipically that the uncertainity on S parameter's phase is 20 degrees abs. for small signal process(due to process)...
Re: Help Reqd ICD2
Be sure that:
1)You have downloaded into the ICD2 the firmware for the 16F's (MPLAB calls it 'Operating system') and that you've the right device selected.
2)If the pic get power from the circuit, be sure that the ICD2 is not powering it and if not, be sure that it does.
