If the NSG 1007 is used through the bus, the :VOLT? MAX query can be used to determine the
maximum allowable rms voltage for the selected waveform. Using the returned value as part of a
program will prevent range errors.
4.4.6Frequency Response Restrictions
The user may create a waveform that contains any number of harmonic frequencies of the
fundamental. The AC Source itself however has a finite signal bandwidth and will attenuate
higher frequency components of the signal. To limit the maximum frequency component of the
output signal, the iX controller automatically applies a band-pass filter to all custom waveforms
as they are downloaded.
The controller implements the following process for user-defined waveforms:
Each down loaded waveform will have a computed frequency limit that is less than or equal the
maximum frequency limit of the AC source. The frequency limit is a function of the harmonics
content of the waveform and will follow the equation below.
Fmax
h
= Fmax/(level * h
n
)
If Fmaxh is below the minimum frequency limit, the waveform will be rejected at down load time
and the label will be deleted from the waveform catalogue.
If the power source is used over the bus, the “:FREQ? MAX” query command can be used to
determine the maximum allowable fundamental frequency for the selected waveform. Using the
returned value as part of a program will prevent range errors.
Limits assume a program of full-scale voltage. No adjustments for voltage setting are made
below the full-scale value.
Waveform selection and frequency programming will be subject to the above limit. An error
message will be generated to reflect this type of error:
"22,Waveform harmonics limit"
Transient editing will also generate the above error during keyboard entry. Remote transient entry
will not check for the error until transient execution.
The frequency domain VIEW mode in the WAVEFORMS menu may be used to visualize the
content of each custom waveform register on the LCD.

4.4.7Switching Waveforms
Waveforms can be switched as part of the transient system. Each transient type setup menu has
a FUNCTION field. This field allows selection of any of the standard or custom waveforms
available in the selected group. Refer to the section on transients for more details on using
transient list to switch output waveforms.
