Entry Default

Description

Peak Off

Toggles peak-hold mode on and off. This function is most useful when assigned to
a function key.

Changes the display update rate in milliseconds. Although values down to zero may
be entered, the minimum display period is actually limited by hardware.

RS232 38400

Change the baud rate in bits per second of the serial port that connects to a host
computer. During firmware download (via the PX3 Utility program), the baud rate
is set automatically to 38400 baud, but it is then restored to the value selected in
this menu entry.

SpanScale

REF LVL

only

Specifies the way the PX3 responds to changes in SPAN. “Off” means do not
change REF_LVL or SCALE when SPAN is changed. “REF LVL only” means
change the reference level to keep the noise level approximately constant. “REF
LVL & SCALE” means also change SCALE to keep the level corresponding to the
top of the screen at a constant level as well.

Span Set

Tap or hold a function key to assign a current SPAN to that key. Once assigned the
function key can be used to set the span with a single key press. The key label
shows the span in kHz.

Step Span

Off

When Off, adjusting the SPAN occurs in 0.5 kHz steps for spans between 2 and 11
kHz, 1 kHz steps for spans between 11 and 102 kHz and in 2 kHz steps for spans
between 102 and 200 kHz. When Step Span is On, adjusting the SPAN occurs in
steps of 2, 5, 10, 20, 50, 100 and 200 kHz.
