Rohde and Schwarz ZNH-K29 - Pulse Measurement Option for ZNH Vector Network Analyzers

The R&S ZNH-K29 option enables precise pulse and peak power measurements using the ZNH together with a Rohde & Schwarz wideband power sensor. Field applications benefit from this compact, powerful combination.

During installation and maintenance of radar systems, pulse characteristics and output power have to be measured. Due to a maximum video bandwidth of 30 MHz and a rise/fall time of < 13 ns, the sensors can measure pulses with a pulse width as short as 50 ns.

When installing and maintaining even the latest generation of microwave link modules, the user benefits from the sensor's high measurement speed and wide dynamic range.

Automatic pulse analysis helps the user measure important pulse parameters. This analysis eliminates the need for complex measurements using markers. Changes in the pulse shape are immediately taken into account in the measurement results.

The following parameters are determined by automatic pulse analysis:

• Time parameters: rise/fall time, start/stop time, pulse width, duty cycle, pulse period
• Level parameters: pulse top, pulse base, peak, average, minimum, overshoot (positive and negative)

Supported measurements

The list below shows which measurements are supported by the ZNH-K29. The achievable RF performance is documented in the datasheet specifications of the R&S NRP-Z81/-Z85/-Z86 power sensors. Please note, power sensors are sold separately.
