How to use measurement limits
The limit facility is useful for placing a guard band around a
measurement.
For example, if the output from a device is +3dBm and must stay
within 1dB of that level, then the limits facility can be used to warn
you if the output rises above 4dBm or falls below 2dBm. Follow this
procedure:
1. Connect the sensor and open the application.
Refer to “Making a measurement” on page 32.
2. Zero the sensor.
Refer to “Zero your sensor” on page 26.
