Brief Description & Key Specifications SI-3033 Software Features...

VSWR vs Frequency
The incident voltage (Vi) and reflected voltage (Vr) are measured using a directional coupler and their plots against frequency are generated.

The VSWR is computed from the Vi and Vr values and VSWR vs Frequency plot is generated.
Cursor gives measurements of Vi, Vr and VSWR at different frequencies.

Spectrum Analysis
Spectrum Analysis of a signal is possible using this mode. Software allows selection of start & stop frequencies, step size and number of steps.
Two spectrum displays can be viewed concurrently and cursor measurement gives values of both traces at the selected frequency.

This eases comparative study of two signals thereby enhances understanding of devices and sources. (especially active devices eg:input vs output of an amplifier).

NETWORK Analysis (Scalar)
This mode allows measurement of Loss or Gain of passive and active devices respectively.
Insertion Loss vs Frequency of cables, Filters, Directional Couplers, etc can be measured.
Likewise Gain vs Frequency of amplifiers can be measured.
Cursors yield measurements of loss/gain at the selected frequency. List giving the frequency and the loss/gain at each step can be scrolled on the PC and can also be saved as a text file.

S-PARAMETERS (Scalar) optional
Scattering parameters (or s parameters) are the most important set of two-port parameters relating to network measurements.
Students can measure the S11, S12, S21 and S22 parameters of different devices and also investigate various factors that effect their performance.
