NOTE
It is possible to set an increment value of greater resolution than can be
displayed or than the hardware can respond to. However, the instrument
records each arrow key press and will respond after the appropriate number
of presses.
START/STOP Encoding If Option 1EP is present and the signal generator is in the
ENCODER mode, the

mode, the
⇑
and
⇓
keys function as the PREV and NEXT keys to change the blinking first
character between each parameter when in the pager encoder mode.
