Storage device
If both USB flash drive and micro-SD card are connected to the instrument, the USB
flash drive takes precedent over SD card as a storage device.
If both storage devices are not connected, the internal memory of the instrument is
used for storage.
The R&S
ZNH can store measurement results and settings in the internal memory,
removable micro-SD card or on a USB flash drive via the USB interface.
Results and settings are always stored together, allowing them to be interpreted in con-
text when recalled. The R&S
ZNH can store at least 100 data records in the internal
memory which are differentiated by their names.
