Fluke PM3082 Oscilloscope 4 Channels 100mhz No Cable
Apparatus should be properly grounded through the protective ground conductor of the power cord. Biasing current for these outputs is provided via V, V and R This is present on all 4 channels.
On the power supply unit there are many parts that carry dangerous high voltages. Adjust the input signal to an amplitude of exactly 6 divisions. For instruments with switchable input impedance it is recommended to make use of this feature. Handle the CRT and its side connections carefully. Main Time Base Description.
Verify that a horizontal line of 4. The balanced input signal for triggering on vertical channels 1,2, 3 or 4 is applied to pin 7 and 8.
In a sequence. Rough handling or scratching can cause the CRT to implode. Properties expressed in numerical values without tolerances, ranges or limits stated, represent the characteristics of an average instrument.
CHIP C Error Calibration step Input Control signal Output As alternative you may use the fast-rise output of the square-wave calibration generator.
Field 1 and Field 2 together form one frame. Page Page – Horizontal deflection; X deflection coef Circuit diagram of external trigger unit TV pattern generator with video output PM test set-up: Apply a 50 Hz sine wave signal of 8 V pp to input CH1; The HF section for frequencies above 5 kHz. The x1 is switched by control signal PA1X1. Probe Adjust signal is distortion-free and has equal intensity.
mp3082 Impedance converter This active stage consists of three sections with different frequency ranges. Input Characteristics Note 1: The principle of the time base is that a capacitor is charged with a constant current. The output circuits are protected against overload by the under voltage protection.
Test equipment Fluke A mode: Remove the rotary knobs.
Oscilloscope 100 MHz PM3082
Recommended Test Equipment Note: The other IC D pm382 the peak- peak detector for the trigger level. After repair and maintenance in the primary circuit, safety inspection and tests, as mentioned in Theseservicing instructions are for use by qualified personnel only.
Page Verify that the deviation from the ideal straight line does not exceed 0. The display part and power supply must be OK.
The linearity of the vertical amplifier is checked by moving a signal with a fixed amplitude vertically over the entire screen area. For the MHz version the corresponding circuit diagram should be used. A second input signal ZT determines the intensity Z component of the text information. This diagram shows the RC-branches and regulators N that give the supply voltages for the various circuits. Page Set CH1 to 0.
This eliminates calibration inaccuracies due to temperature changes. Comments to this Manuals Your Name. Got it, continue to print.
These names make it easier to trace a signal going from one circuit diagram to another. The last possibility is that the rotor makes contact with both stator contacts.
When instrument is switched off or during mains failure. Before turning on the instrument, ensure that it has been installed in accordance with the Installation Instructions, outlined in Section 2 of the Operation Guide. Before soldering, bend the wires through the holes of the solder leads, or wrap the wires around the leads in the form of an open U, or, maintain wiring ridigity by cable clamps or cable lacing.

A range of much finer steps can also be selected. Page The oscilloscope must be capable of displaying signal amplitudes pm0382 are larger than the screen. It can function on a wide range of LINE input voltages. Page DC coupled mode.
