FEATURES |
|
|
|
|
The
Model 3503 and Model 3506 have the
following features: |
|
|
|
|
1. |
A
wow flutter meter and a
frequency counter , these two
instrument in one frame can be
operated independently by
selecting switch. |
|
|
2. |
Wow
flutter is measured with peak
value, average value and RMS
value respectively
in comply with the specification
of each DIN , CCIR , NAB and JIS |
|
|
3. |
PROTRONIX
WOW FLUTTER METER series are
able to measure the weighted wow
flutter ,the linear wow flutter
,the wow and the flutter
respectively. |
|
|
4. |
The
tape speed can be read on the
7-Segement LEDs display of
frequency counter |
|
|
5. |
Linear
meter indicates circuit results |
|
|
6. |
Radio
FM demodulator circuit to detect
△f/fi
is employed |
|
|
7. |
The
error of meter can be checked by
self test .it also can be
trimmed at front panel. |
|
|
8. |
With
handle in the right side of
instrument ,easy to carry . With
two sets of stands , one is wirehold stand in the rear panel ,
another one is foot stand in the
button cover. |

DIFFERENCES
OF MODEL 3503 AND 3506 |
|
|
|
|
Model
3506 has the same specifications as
Model 3503 except the following points: |
|
|
|
|
1. |

|
|
|
Model
3506:6.3KHz±400Hz(DIN), 6KHz±400Hz(CCIR,NAB

|
|
|
Model
3506:6.3KHz±400Hz, 6KHz±400Hz |
|
|
|
The
normal test frequency of Wow Flutter
Meter is 3KHz or 3.15KHz. PROTRONIX Model
3506 is designed for high test frequency
up to 6KHz or 6.3KHz.This is designed
specially for tape recording in high
speed. With Model 3506,it is convenient
to test the tape quality after high
speed recording from Tape Recorder or
Two-Players Recorder. |
