Cursors
RATIO (~Vl, ~V2, ~V) Function
When the 2212 is switched to timebase ( Y-t) mode, you can se-
lect the AVl and AV2 cursors with the AV1/AV2 /AT/1/AT cursor
mode switch.
The delta volts (AVl, AV2, AV) readout is displayed as a percentage
"RA TIO" ( with a vertical signal offive screen divisions correspond-
ing to a ratio of 100%), when:
- The VOL TS/DIV of a selected vertical channel is in the UNCAL
position.
- ADD mode is selected and the CH 1 and CH 2 deflection factors
are not the same (e.g. one vertical channel is in the UNCAL
position, or the VOL TS/DIV settings are not the same).
The delta volts RATIO function is applicable to the A Vl as well as
to the AV2 and to the AV function.
~ VX Cursor Function
When the 2212 is switched to X-Y mode, you can select the AVX
and AVY cursors with the AV1/AV2 /AT/1/AT cursor mode switch.
The AVl cursors become the AVX cursors (vertical lines on the crt).
The AVX cursors represent a crt readout display of a voltage measure-
ment that depends upon:
- The distance between the position of the vertical cursors.
- The CH 2 VOL TS/DIV switch setting.
- The probe coding.
~ VY Cursor Function
When the 2212 is in X-Y Mode, you can select the AVX and AVY
cursors with the AV1/AV2 /AT/1/AT cursor mode switch.
