Spectrum analysis with multichannel view

Deeper insights into device behavior

The R&S®ZNA-K1 spectrum analysis function provides deeper insights into a DUT's behavior where S-parameter measurements versus frequency and power are not sufficient. The software based spectrum analysis function can measure a DUT's spurious and harmonics, providing short sweep times along with high dynamic range and fine frequency resolution. It quickly detects undesired signal components (spurious) in converters and T/R modules.

Features & benefits

Fast spurious search

Faster time to market

The R&S®ZNA spectrum analysis option combines short sweep times, high dynamic range and fine frequency resolution to enable detection of all spurious or unwanted signals from the device under test.

Multichannel view

Deeper insights into component behavior

In multichannel view, numerous results are displayed simultaneously. For example, an S-parameter measurement can be displayed along with the harmonics spectrum, or the conversion loss can be shown along with the spurious signals for a mixer.

Convenient and easy to use

Combined S-parameter and spectrum analysis. When undesired effects are detected during S-parameter measurements, spectrum analysis at the press of a button can identify the root cause. A marker is placed on the desired frequency, and spectrum analysis around this frequency will provide conclusive information about the unwanted effects. A noise marker can be used to display the normalized noise power in dBm (1 Hz).

Available on all ports

Speed and precision

The spectrum analysis function is available on all R&S®ZNA ports. Scalar system error correction boosts accuracy and eliminates influences from the test setup. Independent of the DUT's configuration, the option gives users the flexiblity to focus on the measurement accuracy, eliminating errors caused by awkward cable bends.

Flexibility that counts

The R&S®ZNA-K1 option can be easily installed or retrofitted by a Rohde & Schwarz service center.
