Spectrum Plot - Detailed Display, with Soft ButtonsScreen annotation with important operating parameters including reference level, frequencies, markers, and threshold. In this screen, the user has selected the Peak function. On the screen you see the soft buttons for the Peak function. Note the red marker sitting on the peak and the frequency and amplitude indicated in the upper screen annotation. |

Spectrogram Plot Frequency - Time Plot, Now
there's something you don't get on the traditional spectrum analyzers
(ok, maybe you do get it if you pay enough). This is great
for displaying frequency histories, such as voice prints for example.
|
 |
|
Get
the best of both worlds: Frequency - Time plot
AND Power - Frequency plot. Each plot has it's
advantages, but no need to settle. Get a visual of the time
history and see the real time power spectral peaks at the same time.

Excalibur
adds Phase Analysis to the capabilities of the spectrum analyzer.
In this screenshot, the spectrum analyzer is put into Phase Analysis
mode (Phase menu button) and Zero Span. The input signal is a
sinewave at 105 Hz. The top plot shows the Phase of the input
signal as a funtion of time. The Phase is referenced to the
internal reference oscillator tuned to the Center Frequency (Fc), 100
Hz. The Split Screen plot displays the residual of the input
signal after having been frequency shifted by Fc down to
DC. In this mode the user can compare an arbitrary input
signal to a reference signal and get both a Phase-Time plot as well as
a plot of the Down Converted input signal. Useful in the
analysis of frequency error, or investigation of a phase modulated
signal.

Tracking Generator - Turning this on will make all sorts of cool chirp sounds as the Tracking Generator puts out a sweeping tone synchronized with the capture of the Spectrum Analyzer. Handy for figuring out the frequency response of rooms, coffee cups, etc. Calibration Tone - Just like the big boys, turning this on generates a tone at a programmable frequency. Hint ... if you have a 16 year old daughter, set the tone to 16 kHz and turn up the volume. It will drive her nuts !! (but don't do it when the wife is home, or you may be sleeping on the couch). Input Selector - Select between real time audio input from microphone, line-in, or playback monitor OR select file input. With file input, you browse around to your favorite .wav file. Then as the analyzer sweeps, it plays and analyzes the .wav file. If your handy with software, or you wait for me to write it, you can convert digitized RF to a wav file and analyze your captured RF signals on this very affordable, uber performance laden spectrum analyzer !! Various Fields - These started out as debug fields, but I figured most of you Geeks out there would want to see this info as well (I use Geek most affectionately here). Fs is the sample rate, T is the Sample interval for each sweep, N is the number of samples capture per sweep, Nfft is the number of samples that are FFT'd per sweep (Note that this number can be greater than N .... :-) , Nswp is the number of samples that are displayed per sweep (and this can be larger than N too), File is the file that you selected as the input source if you are running in FILE Input mode, Ptr is a block pointer into the input file, and FFT Overlap is an indicator light that says that we are taking FFTs over more samples than we capture per sweep. |
