Differential attenuator TP-DA25
The Differential attenuator TP-DA25 is a differential 1:25 attenuator, combined with a low noise differential measure lead. It is specially designed to be used with the Automotive Test Scope ATS610004DW-XMSG, Automotive Test Scope ATS605004DW-XMS, Automotive Test Scope ATS5004DW, Automotive Test Scope ATS610004D-XMSG Automotive Test Scope ATS605004D-XMS or Automotive Test Scope ATS5004D, to measure high voltages like e.g. in electrical and hybrid vehicles.
Due to the differential inputs of the scope, a standard attenuator or attenuating oscilloscope probe cannot be used without introducing measuring errors. Instead a differential attenuator is required.
The Differential attenuator TP-DA25 can simply be placed directly on the input of the scope and the test probes directly on the 4 mm banana plugs at the end of the measure lead. The Differential attenuator TP-DA25 has a passive design and does not require a battery.

The inputs of the Automotive Test Scope ATS610004DW-XMSG, Automotive Test Scope ATS605004DW-XMS, Automotive Test Scope ATS5004DW, Automotive Test Scope ATS610004D-XMSG, Automotive Test Scope ATS605004D-XMS and Automotive Test Scope ATS5004D are differential. A standard attenuator or attenuating oscilloscope probe only has attenuation in one signal path, but the differential input requires attenuation in both signal paths. Therefore a standard attenuator or attenuating oscilloscope probe cannot be used without introducing measuring errors.
Instead a differential attenuator like the Differential attenuator TP-DA25 is required, it has attenuation in both signal paths.
Low noise sensitivity
A differential input also means that both sides of the input have a high impedance. There is no connection to ground as in conventional oscilloscopes which are used with coax cables. Using a coax cable on the Automotive Test Scope ATS610004DW-XMSG, Automotive Test Scope ATS605004DW-XMS, Automotive Test Scope ATS5004DW, Automotive Test Scope ATS610004D-XMSG, Automotive Test Scope ATS605004D-XMS or Automotive Test Scope ATS5004D would result in the scope picking up a lot of external interference.
The specially designed Differential attenuator TP-DA25 has a high Common Mode Rejection Ratio (CMRR), it is very insensitive to external interfering signals. The two ends can be placed up to more than two meters apart, while picking up very little interference. With a conventional oscilloscope with a standard oscilloscope probe this is not possible. The maximum distance between the positive side and ground is then usually limited to approximately 20 cm. And this 20 cm is very susceptible to interference. The Differential attenuator TP-DA25 for the Automotive Test Scope ATS610004DW-XMSG, Automotive Test Scope ATS605004DW-XMS, Automotive Test Scope ATS5004DW, Automotive Test Scope ATS610004D-XMSG, Automotive Test Scope ATS605004D-XMS and Automotive Test Scope ATS5004D does not have this disadvantage. External interference is very well suppressed by the special construction of the Differential attenuator TP-DA25. Measuring between two distant points is now possible.
