Dear Sirs,
Thank you for the fast support, the manual does provide all necessary information to repair the radio. All schematics are in a good quality for reading.
The manual fits 100% to my requirements as a technican.
Kind regards Thomas
;
the big video recorder format s-vhs many features delicate in loading system of the cassette. Such machines are no longer manufactured, it would be too expensive.
 ;
THIS MANUAL IS VERY GOOD AND VERY CLEAR
PLEASE NOTE IT DOES NOT CONTAIN THE SETUP INFORMATION TO ALIGHN THE GEARS IN THE CD MECH IT DOES SHOW ALL THE PARTS AND THEIR LOCATIONS .
;
Complete service and operation manual. All schematics are there, all circuit boards AND add-on boards. Including exploded views ,component names and specifications. Also electrical and mechanical adjustment procedures are in this manual. This manual also covers the more advanced BR-S811E unit. Scan quality is fair and usable.
;
High quality scan of original Service Manual. Everything´s fine!
Operating Instructions-7D15 MODES OF OPERATION Manual Stop Watch This mode uses the GATE ON OFF switches to manually turn the counter main gate on and off . The counting rate is determined by the CLOCK switches . Times of up to 10 5 s can be measured in this mode . Event Counter In the EVENTS mode, the 7D15 counters accept information from the B Input connector. The B TRIGGER 1 controls select the counter triggering point. From to . 108 events can be counted in this mode Frequency Measurements The 7D15 can measure frequencies directly from do to 225 MHz when used in the FREQ mode . To obtain greater resolution of low-frequency measurements, measure the period of the waveform and calculate frequency (Frequency = 1/Period). Frequency Ratio Measurements The ratio of one signal to another can be compared with a range of up to 104 :1 and, depending on the range, a resolution of up to 10-7 . In the Frequency Ratio mode, the "standard" or reference signal is usually connected to the EXT CLOCK IN and the signal to be compared is connected to the B Input connector.

Time Interval Measurements (TIM) Two basic modes of time interval measurements can be selected, TIM WIDTH, and TIM A-B . The TIM WIDTH mode measures the time between two points on a waveform . These points are selected by the A TRIGGER controls such that the counter main gate turns on at the point on the waveform selected by the A SLOPE and LEVEL controls and turns off at the same level but on the other slope. See Fig. 2-7c. the TIM WIDTH mode, The TIM A-B mode, like measures the time between two points on a waveform . These two points are controlled individually, such that the A TRIGGER controls select the point on the waveform that turns the main gate on, and the B TRIGGER controls select the point on the waveform that turns the main gate off. See Fig. 2-7d .
Period Measurements and Period Averaging The 7D15 measures periods from 10 ns to 10 5 s . Up to 1000 periods can be averaged to obtain a resolution of up to 10 ps . The period mode measures the time between two points on a waveform . These two points are selected by the A TRIGGER controls such that the counter main gate turns on and off at the point selected by the level and slope controls, see Fig. 2-7a . The period averaging mode holds the
