DIFFERENTIAL MARKERS-A
The frequency readout for all MARKER m conditions has up to 4 significant digits, depending upon the portion
of span measured.
The amplitude readout in dB has a resolution of f .Ol dB for linear scale. The resolution for logarithmic scale
depends upon the LOG m value:
DATA Entry
The minimum incremental change for m frequency is 0.1% of the frequency span.

LOG SCALE
RESOLUTION
One full turn moves the active marker about one tenth of the horizontal
span.
One step moves the marker one tenth of the horizontal span.
Positive entry places marker higher in frequency than the stationary marker,
negative entry places marker lower in frequency. Larger entries than allowa-
ble will place the marker on the adjacent graticule border,
Negative frequencies can be entered using a i m prefix as the minus
sign. For example, to set a m span of 10 MHz with the second marker
positioned to the left of the first, press
