Another excellent buy! A fully readable PDF archive. Good prints!!
It is wonderful done!!! a great job in scanning the manual. Superior quality in all the electric scheme. Very understandable and net!!! Thank you!
muy buen manual por lo completo de este algunos esquemas estan muy divididos lo que hace algo dificil el seguimiento.
very good manual, with detail and clarity in esquematic diagrams and waveforms .
Very quality copy of original service manual, which contains the circuit diagrams, PCB and lists of components, well as recommendation for calibration procedures of device, also everything else, that need for repair, tuning and use this oscilloscope.
All presented copies have high-resolution, so you can view all in detail.
This manual will very useful for simple owners and for repairers.
I recommend these manual, because myself is owner of Philips PM3216 and I need sometimes servicing these oscilloscope (principally calibrating).
Also, these document is an example of excellent design of technical documentation.
3. Mode: Playback
test tape P-4-A100 (10 kHz, â10 dB) L-CH MAIN board CN510 R-CH pin 3 waveform of oscilloscope
CD SECTION [TEST DISC LIST]
pin 1 L R pin 2 V H oscilloscope
Use the following test disc on test mode. â¢ CD: YEDS-18 (PART No. 3-702-101-01) or PATD-012 (PART No. 4-225-203-01) Note: 1. CD Block is basically designed to operate without adjustment. Therefore, check each item in order given. 2. Use YEDS-18 (3-702-101-01) unless otherwise indicated. 3. Use an oscilloscope with more than 10MW impedance. 4. Clean the object lens by an applicator with neutral detergent when the signal level is low than specified value with the following checks.
in phase 45Â° good
90Â° 135Â° 180Â° wrong
4. After the adjustments, apply suitable locking compound to the pats adjusted.
BD91 board oscilloscope
Adjustment Location: Playback Head (Deck A). Record/Playback/Erase Head (Deck B).
Procedure : 1. Connect an oscilloscope to TP106 (FE) and TP124 (VC). 2. Turn the power on. 3. Load a disc (YEDS-18) and actuate the focus search. (In consequence of open and close the disc tray, actuate the focus search) 4. Confirm that the oscilloscope waveform (S-curve) is symmetrical between A and B. And confirm peak to peak level within 3 Â± 0.5 Vp-p.
S-curve waveform symmetry
within 3 Â±0.5Vp-p B
Note: â¢ Try to measure several times to make sure than the ratio of A : B or B : A is more than 10 : 7. â¢ Take sweep time as long as possible and light up the brightness to obtain best waveform.
