Just to review and distribute what we talked about yesterday for the new "Frequency Swept NMR" ("fsNMR") program, below is a description of the two stages of the program you requested.</div>

Stage 1 program<br>
</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
<ul>
<li>To current FRS program, add ability to run multiple scans</li><li>Record and plot X and Y from lock-in amplifier in addition to frequency, R, and theta.</li><li>Average data from each cycle.</li><li>Plot average in background of live data plot after each cycle (how NMR program plots data)</li></ul>
<div>Stage 2 program<br>
</div>
<div>
<ul>
<li>Add ability to read in previous averaging files as background data<br>
</li><li>Add temperature data logging to fsNMR</li><li>normalize new data to background data (new data divided by background data, multiply by peak amplitude of background data)</li><li>save new data's average with background data subtracted.</li></ul>
<div><br>
</div>
<div>We'll start with Stage 1 and go from there. If there's any of the above that is incorrect, please let us know.</div>

<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
A few months ago, I mentioned in a meeting that I was thinking about modifying the FRS program as a back-up for monitoring the target polarization for the UITF experiments. Now we need to realized the plan, since I still have issues with the Zurich Lock-in
Amplifier. </div>

</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
The idea for the modifications is the following:</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">

</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
Stage 1: (in a week or two)</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
<ol>
<li> Make the FRS program capable for averaging of multiple scans with N as a settable parameter.</li><li> Save the averaged data as well as the individual. (The average will be recalled as the background signal.)</li></ol>
<div> This will allow me to determine the NMR signal with comparing the ON resonance and OFF resonance signals, taken with different magnet field settings.</div>
<div><br>
</div>
<div>Stage 2: (expanding stage 1)</div>
<div><br>
</div>
<div> 1. Add the background recall function.</div>
<div> 2. Normalize new signal to background signal.</div>
<div> 3. Subtract the new data with background.</div>
<div> 4. Display the results as data acquired.</div>
<div><br>
</div>
<div>Please give me an estimate on how long it would take to develop each part. We can meet if you need to talk to me. I went to your office yesterday afternoon.</div>
