Key features and key characteristics

The R&S

 

RT

Z1M high-impedance buffer amplifier is an accessory for oscilloscopes

that have only inputs with 50

 

Ω input impedance. It allows you to connect measure-

ment equipment requiring a 1

 

MΩ load impedance to such oscilloscopes.

The R&S

 

RT

Z1M is equipped with the Rohde

 

&

 

Schwarz probe interface to be con-

nected to Rohde

 

&

 

Schwarz oscilloscopes that are compatible with this interface. How-

ever, oscilloscopes that already support a 1

 

MΩ input impedance do not support the

buffer amplifier.

The Rohde

 

&

 

Schwarz probe interface at the buffer amplifier input allows you to con-

nect various probes, e.g. passive probes, current probes, and active probes with
Rohde

 

&

 

Schwarz probe interface.

The R&S

 

RT

Z1M provides an integrated R&S

 

ProbeMeter, which is used for probes

without an own R&S

 

ProbeMeter. Usually, these probes are passive probes.
