1 mVpp to 10 Vpp into 50 Ω, or twice that into an open circuit. Default 100 mVpp into 50 Ω
<
offset
> is the DC offset voltage (default 0), from ±5 VDC into 50 Ω, or from ±10 VDC into
an open circuit.
Output a 5 Vpp pulse wave at 1 kHz with a -2.5 V offset:
APPL:PULS 1 KHZ, 5.0 V, -2.5 V
Frequency
l
The APPLy command must be appropriate for the function. For example, APPL:PULS 300 MHz results in a "Data
out of range" error. In that case, the frequency would be set to the instrument's maximum frequency for a pulse.
Offset Voltage
l
The relationship between offset voltage and output amplitude is shown below. Vmax is the maximum peak voltage
for the selected output termination (5 V for a 50 Ω load or 10 V for a high-impedance load).
|Voffset| < Vmax - Vpp/2
If the specified offset voltage is not valid, the instrument will adjust it to the maximum DC voltage allowed with the
specified amplitude.
From the remote interface, a "Data out of range" error will also be generated.
l
Limits Due to Output Termination: The offset range depends on the output termination setting. For example, if
you set offset to 100 mVDC and then change output termination from 50 Ω to "high impedance," the offset volt-
age displayed on the front panel doubles to 200 mVDC (no error is generated). If you change from "high imped-
ance" to 50 Ω, the displayed offset voltage will be halved. See
for details.

Outputs a ramp wave or triangle wave with the specified frequency, amplitude, and DC offset. In addition,
per-
forms the following operations:
l
APPLy:RAMP overrides the current symmetry setting (
), and sets 100% symmetry for
the ramp waveform.
l
APPLy:TRIangle is simply a special case of APPLy:RAMP. It is equivalent to a ramp waveform with 50% symmetry.
