There is a short video demonstrating the frequency menu
The tinySA scans its input frequency range either in start/stop mode or in center/span mode. The number of points displayed can be selected. The number of points displayed has a maximum but when the RBW is too small to cover the selected frequency range with the selected display points, additional measurements are done and accumulated into the display points.
- START sets the scanning to start/stop mode and sets the start frequency
- STOP sets the scanning to start/stop mode and sets the stop frequency
- CENTER sets the scanning to center/span mode and sets the center frequency
- SPAN sets the scanning to center/span mode and sets the frequency span
- ZERO SPAN sets the scanning to center/span mode, sets the span to 0Hz and sets the center frequency
- JOG STEP sets the frequency step of the jog button. Setting to zero enables an automatic definition of the step size.
- RBW sets the resolution bandwidth. Keep in mind a low RBW may increase scanning time substantially.
- SHIFT FREQ is used in combination with up/down converters and allows entering the actual START or CENTER frequency before the up/down conversion. After activation the "shifted" label is shown at the bottom of the screen. Deactivation of the shift is done by activating the menu entry again. The maximum frequency being displayed is 4.29GHz, any shift must keep the on screen frequencies below 4.29GHz.
- BACK returns to the main menu
The scanning is limited to the frequency range of the selected MODE
