Different mode has different amplitude lower limit; amplitude lower limit may vary in
the same mode if the load is different.
High level upper limit = **
Different mode has different High Level upper limit; High Level upper limit may vary
in the same mode if the load is different.
Low level lower negative limit=**
Different mode has different High Level lower limit; High Level lower limit may vary in
the same mode if the load is different.
High level must be greater than Low level
High level must always be greater than Low level. If the high level is set less than the
low level, the generator will set the low level 1 mV less than the high level
automatically.
Duty Cycle upper/lower limit = **
In the Square mode, different frequency range corresponds to different Duty Cycle
limit.
For a frequency lower than 3 MHz (include), the range is from 20% to 80%;
For a frequency between 3~4 MHz (include), the range is from 40% to 60%;
For a frequency between 4~5 MHz, the Duty Cycle is set to be 50%.
Symmetry upper limit = 100.0%
In the Ramp mode, the Symmetry upper limit is 100%. If the specified symmetry is
greater than 100%, the system will adjust the symmetry to 100% automatically.
Symmetry lower negative limit = 0.0%.
In the Ramp mode, the Symmetry lower limit is 0.0%. If the specified symmetry is
less than 0.0%, the system will adjust the symmetry to 0.0% automatically.
Pulse Width is limited by Period
The Pulse Width should be less than the difference of the period and the Edge Time.
Pulse width lower limit = 8.0ns
In the Pulse mode, the Pulse width lower limit is 8.0ns. If the specified pulse width is
less than 8.0ns, the system will adjust the pulse width to 8.0ns automatically.
Offset upper limit= **
Different mode has different Offset upper limit; Offset upper limit may vary in the
same mode if the load is different.
Offset lower negative limit = **
Different mode has different Offset lower limit; Offset lower limit may vary in the
