4.9.4.1 Editing Output Frequency
Frequency values can be changed using 'Digit' and 'Direct' edit facilities. The editing
processes are not described in Section 3, but follow the same general rules as for editing
voltages.
The resolution of frequency values is set at six significant digits, leading to six frequency
spans of constant resolution.
The thresholds between resolutions of frequency are given in paras 4.9.5.1.
Hardware configurations for frequency change are given in paras 4.9.5.2.
4.9.4.2 Editing High and Low Voltage Levels
High Level and Low Level values can be changed using 'Digit' and 'Direct' edit facilities
as described in Section 3. On the
'Hz' menu screen (illustrated on page 4.9-2) the high level
value is placed on the left, beneath the output frequency value, with the low level value
on the right.
Default Output Waveshape
The default output is a 1kHz symmetrical square wave (equal mark and space durations;
i.e. 50% duty cycle) with its low level at 0 volts, and its high level at +5V, as shown below
in Fig 4.9.1:
