Suggestions for Spectrum/Antenna analyser

[Feynman]

-Rohde & Schwarz FPC1500   with all option  price is more than 6000USD, a bit pricy but options can be bought over time.

At least in Europe there is the "FPC-COM2" package: All options for 4.400 €. Did you check if this package is available in your region?

The MT822x are pretty awesome *except* for amplitude accuracy

At first glance Rigol's published best case specifications look nice compared to Anritsu's worst case specifications, but I think you would prefer the Anritsu more in the long run.  Its good typical accuracy, better design, better endurance and life make the Anritsu the choice of the professionals, not the Rigol.  While the Anritsu has good actual frequency accuracy without it, the GPS option is nice.

Since I own a MT8222A, I thought that I would provide some examples of measurements made with it.

The first shows the VSWR of a broadcast TV antenna.  The attachments were prepared using the free Anritsu software.  The marker frequencies were added after the measurement using the Anritsu software.  The channel information was added by PhotoStudio software.

The second attachment is a Smith Chart of a different antenna.  Since the VSWR was so good I have a zoom of the chart to better show the details.  Note the antenna resistance and reactance on the marker frequencies.

The third attachment shows a transmission line sweep.  The markers are at connector points, with the final one being at the antenna.

The fourth attachment shows the frequency response of a filter while the MT8222A is in the "Gain" mode.  It is acting as a spectrum analyzer with a tracking generator.  Again, the markers were added after the fact.

The fifth attachment shows my measurement of the 99th harmonic of a 10 MHz GPSDO.  Note the 10 Hz span with a 1 Hz RBW.  The 99th harmonic is measured as less than 0.1 Hz off frequency.

The final attachment shows the measurement for a harmonic around 4.88 GHz.  Note the levels being measured: -160 to -170 dBm.  I am going to extreme to show compliance with the FCC -110 dB requirement.

Hopefully the attachments allow you to better evaluate the MT8222A.
