< Undo reverts to the start and stop frequencies that existed directly before the
Start=M1/Stop=M2 key was pressed.
More 1 of 2 selects a further set of function keys that provide an additional method
for changing the start and/or stop frequencies based upon the frequency step size:
Fix Start fixes the start frequency at its present value so that the Step
Up/Down keys operate only on the stop frequency. The word Fix appears
against the start frequency at the top of the screen. Pressing the key
again cancels the function. Fix Stop performs a similar function to Fix Start for the stop
frequency.
Step Up/Step Down increases or decreases the start and stop
frequencies by the current step value. If Start or Stop has been ‘fixed’
only the other frequency will be stepped.
More 2 of 2 cancels Fix Start or Fix Stop and selects the previous set of function
keys.
4.3.5 Frequency/Span > Step Size
Sets the size of frequency stepping using the Step Up/Down keys.
Set Step brings up a numeric keyboard from which the desired frequency can be
entered in MHz to a resolution of 0.001 (1kHz). Pressing ‘Set by Tab/Jog’ from this
screen provides an alternative frequency editing mode. Pressing ‘Set by K/B’ from
this screen returns to the numeric keyboard setting screen. Pressing ‘Exit’ returns to the main
Centre menu. The last used mode (K/B or Tab/Jog) is retained.
Auto Span/10 causes the step size to be automatically linked to the width of the
span so that the step equal one graticule division.
Set to Mdelta sets the step size equal to the frequency difference between the M1
and M2 markers (if active).
Set to Centre sets the step size equal to the centre frequency.
Set to M1 sets the step size equal to frequency of the M1 marker.
4.3.6 Frequency/Span > Frequency Presets
Provides a quick method of storing and recalling frequency ranges (centre+span or
start+stop). No other parameters are stored or recalled.
Full Span sets the frequency range to 1MHz to 2700MHz or 1300MHz.
Store Preset creates a pop-up menu of six preset numbers. Pressing a key in the
pop-up stores the current frequency range into that preset position. Any existing
frequency range will be over-written.
Recall Preset creates a pop-up menu of six preset numbers. Pressing a key in the
pop-up sets the frequency range that has been stored in that preset position. If
nothing has yet been stored in that position, an error message will appear.
Toggle Last restores the frequency range that existed prior to the last preset being
recalled.
