SA2500X Specifications

Definitions and Conditions

Specifications are typical and are published as general information to the user.

Specifications are valid under the following conditions unless otherwise noted.

  • SA2500X warmed up for at least 30 minutes
  • Environmental conditions within the probe's specified limits

Electrical Specifications

Attenuation ratio

10:1, ±0.5% (DC)

Dynamic measuring range

±8 V

Bandwidth (probe only)

2.5 GHz

Maximum rated input voltage

20 V

Notice Applying input voltages outside the specified limits can destroy the probe's amplifier.
  • To counter harmonic distortion and avoid input linearity errors, the maximum amplitude of the input signal should not exceed the dynamic measuring range limits stated by Figure 1.
  • To avoid damage to the probe, the maximum amplitude of the input signal may not exceed the maximum input voltage limits stated by Figure 1.

Input Impedance

Measurement Category

CAT O

Caution Do not connect the SA2500X to signals or use for measurements within Measurement Categories II, III, or IV.
Attention Ne connectez pas le SA2500X à des signaux et ne l'utilisez pas pour effectuer des mesures dans les catégories de mesure II, III ou IV.

Measurement Category I is for measurements performed on circuits not directly connected to the electrical distribution system referred to as MAINS voltage. MAINS is a hazardous live electrical supply system that powers equipment. This category is for measurements of voltages from specially protected secondary circuits. Such voltage measurements include signal levels, special equipment, limited-energy parts of equipment, circuits powered by regulated low-voltage sources, and electronics.

Note Measurement Categories CAT I and CAT O are equivalent. These test and measurement circuits are for other circuits not intended for direct connection to the MAINS building installations of Measurement Categories CAT II, CAT III, or CAT IV.
