Impedance
50 Ohm 75 Ohm Other
Press this soft key to toggle the impedance setting to 50 Homs, 75 Ohms, or Other impedance value. Choosing 75 Ohm selects the 7.5 dB loss of the Anritsu 12N50‑75B adapter. For other adapters, choose Other and enter the appropriate loss value.
Auto Ref Level
Press this soft key to set the Auto Reference Level, which adjusts the position of a signal on the display screen so that it is approximately two divisions down from the top, if possible. When the key is pressed, the reference level is adjusted once. Auto Ref Level has no effect on the settings for the preamplifier or the vertical scaling. This soft key is displayed only for MS20xxC instruments.
