APPLy Subsystem

Parameter Typical Return

<frequency> in Hz, default 1 kHz (none)

<amplitude> Desired output amplitude in Vpp, Vrms or dBm, as specified by

VOLTage:UNIT.

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 OUTPut[1|2]:LOAD for details.

Outputs a ramp wave or triangle wave with the specified frequency, amplitude, and DC offset. In addition, APPLy per-

forms the following operations:

l APPLy:RAMP overrides the current symmetry setting (FUNCtion:RAMP:SYMMetry), 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.
