BESSEL Application Note (PDF)
  

S-5022 Spectrum Analyzer offers unique performance and measurement capabilities specially suited for Educational Applications. Swept Synthesized Software measurements offer greater accuracy of frequency as well as amplitude compared to conventional low cost Spectrum Analyzers. Spectrum hardcopy is available via centronics interface and PC connectivity is via RS232 serial port.

STS-3024 Spectrum/Network (Scalar) Analysis Software greatly enhances the scope of Usage and Experimentation in the Lab. There are Four Modes of operation as described below.




SPECTRUM Analyzer Mode

User can set the Start/Stop frequency, step size and no. of steps for the Spectrum measurement. Cursor yields measurement of Freq and dBuV. Above shows the Spectrum of TV Signal CH58 showing Carrier with Chroma & Aural Sidebands

NETWORK (Scalar) Analyzer Mode

This mode is very useful for testing Passive/Active devices for Loss or Gain. The Cursors directly indicate the loss/gain at the selected frequency. This is very cumbersome using a conventional Spectrum Analyzer




MICROSTRIP FILTER

Microstrip Filter shown above was tested using the Network Analyzer Mode. The above shows an insertion Loss of 4.9dB at 608MHz.

HARMONIC Mode

In this mode the user can enter the Fundamental freq, select the Harmonic No (max 50th). All measurements are diaplayed in Bar Graph. Cursor indicates the Harmonic No and Percentage. Above shows the Harmonic content of a 10MHz Square Wave upto the 50th harmonic

METER/DIGITAL/BAR Mode


At User selected Frequency the dBuV is indicated as Digital readout and Analogue Meter/Bar. Amplitude Stability or Fine Adjustments are Monitored with ease using the Meter or Bar as compared to a Digital readout of a parameter
