Meas Out
The direct generator/receiver access can be used to insert external components (exter-
nal signal separating devices, power amplifiers, extension units etc.) into the signal
path. This feature enables custom measurements, e.g. to test high-power devices or to
extend the dynamic range.
If no external components are connected, each Out/In loop must be closed using a
jumper.
Maximum input levels
The maximum RF input levels at all SMA inputs must not be exceeded.
In addition, it is important that the signal fed in at the SMA inputs contains no DC off-
set. A DC offset can impair the measurements and can even damage the instrument.
See the front panel labeling and the data sheet for applicable limits.
USB Connectors
The front panel offers three USB connectors of type A (master USB).
The USB ports can be used to connect external devices, e.g.:
●
external PC accessories such as mouse or other pointing devices, a keyboard,
printer or external storage device (USB stick, CD-ROM drive etc.)
●
external measurement equipment such as calibration units, power meters, fre-
quency converters, extension units, signal generators, or switch matrices
