Key Path Key Path Channel Setup Menu Scale The Scale softkey controls the vertical scaling of the waveform If the fine mode is off then the knob and arrow keys change the vertical scaling in a 1 2 5 sequence When fine mode is on the knob and arrow keys change the vertical scaling in 1 mV increments You can also use the keypad to enter values in 1 mV increments independent of the fine mode selection The units the scale is displayed in depend on the unit of measure selected with the Units softkey The choices for units are volts watts amperes or unknown Channel Scale Offset The Offset softkey moves the waveform vertically It is similar to the position control on analog oscilloscopes The advantage of digital offset is that it is calibrated The offset voltage is the voltage at the center of the graticule area and the range of offset is 500 mV You can use the knob arrow keys or keypad to change the offset setting The fine mode also works with offset When an Agilent 54700 series active probe is used with the plug in module and is connected to the probe power connector adjacent to the channel input the offset control adjusts the external scale factor and offset of the hybrid inside the active probe A probe connected to the auxiliary power connector adjacent to the trigger input will function but the channel scale factor will not be adjusted automatically Channel Offset 2 5 FINAL TRIM SIZE
