1/~T and PHASE
Cursor Function
5 - 36
With the 2212 in the Y-t mode, and the cursor mode switch in the
reciprocal delta time function (1/Llt), two vertical cursors are dis-
played on the screen, and the crt readout displays:
- The reciprocal of the delta time difference (frequency) in Hz.
- The PHASE, with five horizontal screen divisions corresponding
to a phase of 360 degrees.
1/L1T Function
With the cursor mode switch in the 1/LlT position, the 1/LlT fre-
quency is determined by :
- The distance between the two vertical cursors.
- The SEC/DIV scaling as defined by the SEC/DIV switch.
- The setting of the Xl, Xl0, X50 magnify switch.
PHASE (1/L1T) Function
With the SEC/DIV switch in the UNCAL position in the Non-Store
mode, the 1/ Llt cursor difference is expressed as "PHASE", in de-
grees("), with five horizontal screen divisions corresponding to a
phase of 360 degrees (see Table 5-4).
