FUNCTION GENERATOR CHARACTERISTICS (Continued)
Maximum number of points per basic waveform Local: 3933
Remote: Can be set to either 3933 (normal resolution- default value) or 5760 (high
resolution), using the LIST:RES command.
• Each basic waveform (sine, triangle, ±ramp, square and level) is constructed using
a different number of points, depending on the basic waveform, type and fre-
quency. The number of points is inversely proportional to the frequency. For exam-
ple, a "local" sine segment of 0.01Hz uses almost the maximum number of points,
3840. Similar, a single segment of a "remote" high resolution sine segment at a
frequency bellow 1Hz uses the maximum number of points, 5760.
• Due to the different number of points of the basic waveforms (except square and
level) THD-F (Total Harmonic Distortion relative to the fundamental frequency)
and linearity for ramp and triangle waveforms are frequency dependent. For exam-
ple for a sine segment, the THD-F is 5% at 400Hz and 1.6% at 40Hz.
Count (Number of repetitions) Range: 1 to 255
For Count = 0 the waveform is exe-
cuted indefinitely until stop com-
mand is sent
• Local: When the count is complete or if
execution is stopped using
%
, the output
of the unit is set to OFF (Standby indicator
lit). Output must be enabled (press
STANDBY) to execute the waveform
again.
• Remote: When the count is complete or
the waveform is stopped using the
VOLT:MODE FIX command, the output
gpes to zero (main channel reference pro-
grammed to zero).
Waveform Name 10 characters maximum
Waveform Parameters Type: Voltage or Current
Positive Protection Limit:
(Vd-c or Ad-c)
Negative Protection Limit:
(Vd-c or Ad-c)
Count: number
Initial/Repeating
• Type of waveform, voltage or current, can
be selected only for a new waveform and
consequently applies to all waveform seg-
ments. Changing the type for an existing
waveform is not possible, unless the wave-
form is erased first.
• The Limit values (positive/negative) and
the count number apply to all waveform
segments and can be edited at the begin-
ning of a new waveform or later when mod-
ifying a waveform (see PAR. 3.3.9.7).
• All segments except the last may be set to
run once (Initial) or per the Count setting
(Repeating).
Basic waveform parameters Sine: Frequency (Hz), Amplitude (Vp-p or Ap-p), Offset (Vd-c or Ad-c),
Start Phase (°), Stop Phase (°).
Triangular: Frequency (Hz), Amplitude (Vp-p or Ap-p), Offset (Vd-c or Ad-c), Start
Phase (°), Stop Phase (°).
Ramp (Pos. or Neg.): Frequency (Hz), Amplitude (Vp-p or Ap-p),
Offset (Vd-c or Ad-c).
Square: Frequency (Hz), Amplitude (Vp-p or Ap-p), Offset (Vd-c or Ad-c).
Level: Timing (sec), Amplitude (Vd-c or Ad-c).
• Local: the Start/Stop phases, available for sine and triangle only, can be set or
edited by modifying the existing segment (see PAR. 3.3.9.7).
• Remote: the start/stop phases are global parameters, applicable to all sine/ trian-
gular waveform segments.
• The Start/Stop points are independent and can have any value between 0° and
360°.
