H
ERROR ONLY — This is the factory default. A beep occurs only when the
2715 issues an alarm, error, or warning message. The alert sounds only once,
even if the condition repeats and a displayed message is repeated.
H
KEYCLICK & ERROR — Combination of KEYCLICK ONLY and
ERROR ONLY modes.
Switch the audio alert to the setting of your choice.
Minimum signal size is the smallest amplitude difference that must exist
between signal peaks for them to be recognized as separate peaks during Next
Higher and Next Lower or Marker arrow operations. It is expressed in bits; full
scale being 255 bits. The minimum value is 2 bits; factory default is 20 bits or
approximately 8% of full scale (three minor divisions).
1. Press [1] to select MINIMUM SIGNAL SIZE from the Instrument Configu-
ration menu.
2. Type a new value and enter it by pressing [W].
The new value appears at the end of item 1.
3. Experiment if you want, then restore the factory default value.
NOTE
. This feature is used primarily for certain procedures at the factory; we
recommend that you leave WAVEFORM TO PRINTER turned off.
Item 2 of the INSTRUMENT CONFIGURATION menu, WAVEFORM TO
PRINTER ([UTIL] [4] [3] [2]), sends a binary or ASCII representation of the
displayed waveform to the serial port following each sweep. The 2715 must have
the RS-232 port installed, and PRINTER CONFIGURATION must be set to
TTY00 ([UTIL] [4] [2] [0]).
Item 2 toggles data transmission ON and OFF, and item 3 toggles the data format
between ASCII and binary.

CALIBRATOR
The 2715 uses internal reference oscillators to analyze the input signal. At wide
spans, a slight amount of drift in an internal oscillator is not noticeable.
However, as the span is reduced to a few kHz/div or less, any internal oscillator
jitter becomes apparent. The on-screen indication is phase noise close to the base
