The R&S RT‑ZA15 is an external 10:1 attenuator for the R&S RT‑ZD10/20/30 differential probe. It extends the input voltage range of the R&S RT‑ZD10/20/30 probe. Both dynamic range and operating voltage window are increased.

The combination of R&S RT‑ZA15 external attenuator and R&S RT‑ZD10/20/30 differential probe has the following key characteristics:

• Attenuation 100:1
• Bandwidth:
• DC to 1.0 GHz (with R&S RT-ZD10)
• DC to 1.5 GHz (with R&S RT-ZD20)
• DC to 2.0 GHz (with R&S RT-ZD30)
• Dynamic range (differential input) +/-50 V with +/-50 V offset capability
• Differential input resistance 1 MOhm
• Differential input capacitance 1.3 pF
