(7) While observing waveshape in figure 8, adjust WAIT ADJ (fig. 3) for a wait time

of 1 ms (R).

16. Source Relationship

NOTE

The frequency accuracy of the TI is dependent on the +16 V

reference supply, the -16 V reference supply, the 32 V p-p

ramp, and the inverted 32 V sweep ramp. These four voltages

must be precisely adjusted in relation to each other to maintain

dial and display accuracy. (See figure 9.)
