<p>We have an Agilent N5230A 20 GHz 4 port VNA with an N4433A ECal plus a 85052B mechanical calibration kit. We use SPView III with our VNA and Hyperlynx for documentation and S-<wbr />parameter processing.</p>
<p>We use Tektronix DSA8300 with 80E04 20 GHz/80E10 50 GHz sampling heads with TDR. We can use those to characterize model devices in the time domain and with Tektronix's IConnect TDR based analysis software we can convert the time domain data into simulatable models. </p>
<p>For TDR we have an Agilent N5230A 20 GHz 4 port VNA with an N4433A ECal plus a 85052B mechanical calibration kit. We use SPView III with our VNA and Hyperlynx for documentation and S-<wbr />parameter processing.</p>
