PSM1700 PsimetriQ user manual

3.2 Numeric data entry
Parameters such as frequency and offset are entered as
real numbers; frequency is an example of an unsigned
parameter, offset is an example of a signed parameter.
Real numbers are entered using the number keys,
multiplier keys, decimal point key, or +/- key (if signed
value is permitted). When the character string has been
entered, pressing the ENTER key sets the parameter to the
new value. Until the ENTER key is pressed, pressing the
HOME key aborts the data entry and restores the original
number.
If a data value is entered that is beyond the valid limits for
that parameter then a warning is issued and the
parameter set as close to the requested value as possible.
For example, the maximum amplitude of the PsimetriQ
generator is 10V peak; if a value of 15V is entered, a
warning will be given and the amplitude set to the
maximum of 10V.
When the parameter is first selected there is no character
cursor visible – in this condition, a new number may be
entered directly and will overwrite the existing number.
To edit a data value rather than overwrite it, press the
RIGHT key and a cursor will appear. New characters are
inserted at the cursor position as the keys are pressed, or
the character before the cursor position can be deleted
with the DELETE key.
Data values are always shown in engineering notation to
at least 5 digits (1.0000-999.99 and a multiplier).
