Fluke 125 120 Series, 40MHz Handheld Digital Oscilloscope, 2 Analogue Channels

The Fluke 125 ScopeMeter features the same specifications as the 124 and the additional functions detailed below

Bus types: AS-i (EN50295, 166 kb/s); CAN-bus (ISO-11898, up to 1 Mb/s); Interbus S (EIA-485, up to 10 Mb/s); ControlNet (61158 type 2, 5 Mb/s); Modbus (EIA-232 up to 115 kb/s and EIA-485 up to 10 Mb/s); Foundation Fieldbus H1 (61158 type 1, 31.25 kb/s) and H2 (61158 type 1, up to 10 Mb/s); Profibus DP (EIA-485 up to 10 Mb/s) and PA (61158 type 1, 31.25 kb/s); Ethernet (10Base2 [coaxial] and 10BaseT [UTP]), 10 Mb/s; RS-232 (EIA-232, up to 115 kb/s); RS-485 (EIA-485, up to 10 Mb/s); or user-defined system
Measured parameters (where applicable): Baud rate, rise time, fall time, high level, low level, distortion, amplitude and jitter, compared with a standard set of values

This function directly analyses the electrical signals of the network to provide a waveform and measure individual parameters. The results are then compared with standard parameters and a good or bad indication is displayed.

Measured values: Watt, VA, VAR, Power Factor (PF); power configuration: single-phase or balanced three-phase (delta-configuration) mains supply
Voltage measurement: Channel A, using STL120 voltage probe or direct input
Current measurement: Channel B, using i400s current clamp (included) or another compatible current clamp with the following sensitivity: 0.1 / 1 / 10 / 100 / 1000 mV/A, 10 mV/mA and 400 mV/A.

Analysed waveform: voltage (Ch.A), current (Ch.B) or power (Ch.A x Ch.B), automatically generated
Harmonics frequency range: DC up to 33rd harmonic (fundamental ≤60 Hz); DC up to 24th harmonic (fundamental ≤400 Hz)
Display: bar graph showing 1st up to 33rd harmonic and DC; amplitude displayed in % relative to fundamental
Timebase setting: 5 ms/div
Measurements: relative amplitude of individual harmonics; THD in %r or %f

Converts waveform information into a harmonics display (using FFT processing), which shows the relative amplitude from the first to the 33rd harmonic

Model 125/S is also available (331-109), which includes the ScopeMeter 125, C120 hard case,
OC4USB interface cable and FlukeView SW90W (ScopeMeter) software
