Page 10: Calibrating The Lds-910 Plus
Calibrating the LDS-910 Plus: The LDS-910 Plus Receiver can be calibrated to the transmitter with an offset value so it shows the shield effectiveness on the screen. These procedures will outline testing in the ISM band of 902-928Mhz. This procedure should be repeated every time the unit is used to ensure accurate readings. The calibration procedure is shown below. -
Page 11: Test Procedure
receiver can read from +30db to -90db. With the attenuator disabled, the unit will read from -10 dB to -120db. The transmitter will output at values greater than -10db, so unless the attenuator is enabled for calibration the value will not be shown. Similarly, if the attenuator is enabled while testing, the dynamic range will be severely limited.
