      產品詳細介紹Product Introduction

      DIFFERENTIAL BROADBAND PROBES
      A flat frequency response and a high input impedance with low input capacitance permit precise measurements on differential signals while keeping the loading on the DUT low. The high common mode rejection over the entire probe bandwidth ensures high immunity to interference. Special browser adapters allow flexible contacting with high signal fidelity.

      High common mode rejection
      Differential signals are used especially at high clock rates to effectively suppress common mode interference and to transmit broadband signals without errors. These signals can be measured accurately only by using differential probes. Common mode rejection is an important quality parameter. Rohde&Schwarz differential probes suppress common mode interference over the entire probe bandwidth.


      Low loading at DC and high frequencies
      In the case of DC voltage, a distinction must be made between the input impedance for differential and common mode signals. This is particularly important when measuring low voltage differential signaling (LVDS) lines, for example. Although the differential input impedance of LVDS receivers is typically 100 Ω, the operating point is often set at high impedance. Excessive loading on the signal line can shift the operating point outside of the receiver's input voltage range and impair the functioning of the circuit. Almost all Rohde&Schwarz differential probes have a very high differential input impedance of 1 MΩ and a common mode impedance of 250 kΩ, ensuring that the loading remains low.



      Wide dynamic range expands the range of applications
      The wide dynamic range of ±5 V with an additional offset compensation of ±5 V (differential mode) and ±22 V1) (common mode) of the R&S®RT-ZD10/20/30/40 differential broadband probes make them universal measurement tools. High-speed, single-ended signals at DDR storage ports are just as easily measured as symmetrically fed RF signals or voltages without reference to ground in switching power supplies.

      The R&S®RT-ZD10 active differential probe, together with the included R&S®RT-ZA15 external attenuator, permits the measurement of voltages up to ±60 V DC/±42.4 V AC (peak) at a bandwidth of 1 GHz.

      Focus on usability
      When designing the probe accessories, Rohde&Schwarz paid particular attention to usability. Clear identification of the positive and negative inputs, an extensive array of probe tips, easy and precisely adjustable pin offset and spring-loaded tips for the browser adapters are only a few of the special features. 1)
      This option is available for the R&S®RT-ZD20/30/40 starting with serial number 200000.
