Agilent Technologies manual Output Amplitude, Offset Voltage Limitations, U2761A User’s Guide

Features and Functions 2

Remote Interface Operation

FREQuency {<frequency>}

You can also use the APPLy command to select the function, frequency, amplitude, and offset.

Output Amplitude

The default amplitude is 1 Vpp (into 50 Ω) for all functions.

Offset Voltage Limitations

The relation between the output amplitude and offset voltage 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).

Vpp ≤ 2 ⋅ (Vma x – Vo ffs et

)

Limits Due to Output Termination

If you change the output termination setting, the value of the output amplitude will be adjusted (and no error will be generated).

For example, if you set the amplitude to 5 Vpp and then change the output termination from 50 Ω to “high impedance”, the amplitude value will double to 10 Vpp. If you change from “high impedance” to 50 Ω, the displayed amplitude value will drop to half. For more information, see “Output Termination” on page 36.
