saves the current limit-line tables in the current mass-storage device (spectrum
analyzer memory or memory card). To verify the current mass-storage device,
press SAVE LIMIT. If MAX REG # appears on the spectrum analyzer display,
the current mass-storage device is spectrum analyzer memory. If PREFIX= is
displayed, the memory card is the mass-storage device. Press ISAVE) or (RECALL),
then INTERNAL CARD to change the current mass-storage device. Press
SAVE LIMIT, enter a register number, then press [ENTER] to save the current
limit-line table in spectrum analyzer memory or on the memory card. When
saved on the memory card, limit-line tables are stored with “1-“, the prefix,
and the register number entered. When saved in spectrum analyzer memory,
the register number is saved in a trace register. Trace-register values are
restricted to a range between 0 and the number x indicated by MAX REG # = x.

scales the vertical graticule divisions in logarithmic units when LOG is
underlined. When the SCALE LOG LIN function is the active function,
the logarithmic units per division can be changed. Values may range from
0.1 to 20 dB per division. When LIN is underlined, the vertical scale is in
linear mode which has a range of 1 kW to 1 pW. The reference-level value is
set to the top of the screen and the bottom graticule becomes zero volts. (Each
division of the graticule is one-eighth of the reference level in volts.)
Pressing SCALE LOG LIN always sets the units specified for the current
amplitude scale. Pressing [PRESETS) or powering on the spectrum analyzer sets
the default units.

triggers on the SECAM-L video formats. Pressing SECAM-L alters the TV line
number that the spectrum analyzer triggers on internally; the line number
displayed when TV LINE # does not change. Pressing SECAM-L changes the
video modulation to positive; set TV SYNC NEG POS to NEG if negative video
modulation is required.

selects one of the four possible markers. A marker can be turned on once it is
selected. A marker that has already been turned on will become active when
it is selected. If a marker has already been turned on and assigned to a specific
trace it will become active on that trace and the MK TRACE AUTO ABC softkey
will have the appropriate trace letter underlined.

AMPLITUD
allows you to enter either the amplitude value for the displayed (upper
or lower) limit-line segment or the amplitude value for the current
amplitude-correction point. Enter the amplitude value for the selected
frequency or time by using the data keys. Change an amplitude value by using
the step keys or the knob. Press (SPJ to correct errors.
Front-Panel Key Access: m or (DISPLAY)
SELECT
DLT AMPL
allows you to enter the delta amplitude value. The middle amplitude value and
the delta amplitude value create an upper and lower limit-line segment. Enter
the delta amplitude value for the selected frequency or time by using the knob
or data keys. Press m to correct errors. The default value is 0.
