5. To configure connected external instruments, use the "System Config > System
Configuration > External RF and I/Q" dialog.
The parameters defining the voltage level of the output signal are interdependent.
Consider the limits listed in "Maximum overall output voltage" on page 466.
Maximum overall output voltage
The voltage of the analog output signals is defined as a combination of output voltage
of the I and Q signal components and an optional bias voltage. If the differential output
is used, an additional offset can be set, too. The values of these parameters are inter-
dependent so that the magnitude of the sum of output voltage and bias voltage must
not exceed 4V.
The following applies:
●
Single ended signal:
V
p
+ V
bias
≤ 4 V
●
Differential signal:
0.5*V
p
+ |V
bias
| + 0.5*V
offset
≤ 4 V
Where:
●
V
p
is the output voltage as set with the parameter I/Q Level Vp EMF
●
V
bias
is the bias voltage as set with the parameter Bias (EMF)
●
V
offset
is the offset between inverting and non-inverting output as set with the
parameter Offset (EMF)
