Fig 6-7: RB-DMA2 Frequency and Sync Rotary Switch Selections.

Test/Calibration Mode
For optimum performance of the RB-DMA2, the unit should be calibrated when it has been
powered up for approximately 10-15 minutes. The circuitry and chipsets contained in the
unit will warm up during this time and the performance will deteriorate unless calibrated
(the noise floor and dynamic range will be 1-2dB lower than the best possible performance).
The calibration cycle calibrates the gain and the zero reference of the A/D converter.
To calibrate the RB-DMA2, set the rotary FREQUENCIES AND SYNC MODES switch to position
"F". The power LED on the front panel will flash quickly for 2 – 3 seconds and will illuminate
fully when the unit is calibrated. Once calibration is complete, reset the rotary switch to the
position that you require.
