Demo Mode/Simulator

The simulator generates pseudo random values or other pre-defined measurement sequences that are processed by the software just as real power measurements would be processed. The MB-1 simulator is useful for checking the calibration of a Panel Meter or Coupler. It is also the easiest way to familiarize yourself with MB-1's features without running live.

There are six different simulation modes  that are covered in detail in the User's Manual. Each is useful in a particular situation. For example, the sweep mode generates a linear sweep of simulated values from 0 to the full scale value of the selected coupler. If you run this simulated mode using an analog Panel Meter that that has a similar full scale value, the needle should rise smoothly with no discontinuities.

Below, the internal crossneedle meter has been calibrated and we are checking its calibration using the simulator. In this example, Virtual coupler 5 is being used and has been programmed to generate a pseudorandom set of power samples between 0 watts and 20 watts. The SWR has been programmed for a value 3.0. The intersection of the Forward and Reflected needles should always intersect at the SWR=3 curve for all forward and reflected power samples.

Crossneedle Meter to verify its Calibration

(Note - The 7-segment bezel that is shipped with the kit is a darker shade than the one shown above, and hides the non-illuminated LEDs.
It uses the same material shown here, but has the polished beveled edges and socket mounting screws as shown above.)

 Crossneedle Meter and the
External Display Modules

In the figure above, the Simulator is programmed to generate an SWR value of 2.5. The current Bar Graph settings, as shown on line 4 of the LCD are as follows:

        Display Devices: BOTH internal and external Bar Graph are on
        Display Mode:      Bar Graph is displaying SWR
        Bar Graph Full Scale value  3.0
        Sticky Bar: OFF
