Limits Due to Amplitude:
You can set the voltage levels to a positive or negative value with the restrictions shown
below. Vpp is the maximum peak-to-peak amplitude for the selected output termination (10 Vpp into 50 Ω or 20
Vpp into an open circuit).

Differences between remote and front panel operation:
l
Remote Interface:
Setting the high or low level from the remote interface can change the high level or low
level to achieve the desired setting. In this case either a "Data out of range" or "Settings conflict" error will
occur. If the high level is set below the low level, the instrument will set the low level 1 mV less than the high
level. If the high level is set below the LOW limit or the instrument output specifications, the low level will be
set to the LOW limit or instrument output specification and the high level will be set 1 mV above the low level.
A similar set of rules applies if the low level is set incorrectly.
l
Similarly, the low level can be set above the high level from the remote interface. In this case the instrument
will set the high level 1 mV larger than the low level. If the low level is set higher than the HIGH limit or the
instrument output specifications, the high level will be set to the HIGH limit or instrument output specification
and the low level will be set 1 mV below the high level.
l
Front Panel:
Setting the high or low level from the front panel may clip that level setting in order to achieve
the desired level setting, and a "Data out of range" error will be generated. The high level cannot be set below
the low level from the front panel.
l
Note that when you set the high and low levels, you are also setting the amplitude and offset of the waveform. For
example, if you set the high level to +2 V and the low level to -3 V, the resulting amplitude is 5 Vpp, with a -500
mV offset.
l
Limits Due to Output Termination:
If you change the output termination setting, the displayed voltage levels will
be adjusted (and no error will be generated). For example, if you set the high level to +100 mVDC and then
change the output termination from 50 Ω to "high impedance", the amplitude displayed on the front panel will dou-
ble to +200 mVDC. If you change from "high impedance" to 50 Ω, the displayed amplitude will be halved. Chang-
ing the output termination setting does not change the voltage present at the output terminals of the instrument.
This only changes the displayed values on the front panel and the values queried from the remote interface. The
voltage present at the instrument's output depends on the load connected to the instrument. See
for details.
l
Limits due to VOLTage:LIMit:STATe command:
If the voltage limits are enabled, the level settings are checked
against the specified limits (
) before a change in level is executed. If a
change in output level would exceed a LIMIT setting, the level is clipped to the maximum (or minimum) value
allowed that will not exceed the LIMit setting and a "Settings conflict" error will be generated.
