L'explication/l'anotation:For visual observation and measurement of parameter of amplitude-frequency
characteristics on crt screen in the range of frequencies
from 0, 2 to 2100 kHz
La description détaillée de marque:Ï-326-3 is intended for visual observation and measurement of parameter
amplitude-frequency characteristics on the screen of electron-beam
pipe in the range of frequencies from 0, 2 to 2100 kHz while exercising in
set with measuring generator of Ï-326-1 of tuning and
field measurements of channels and group trunks of multi-channel
long-range communication systems, as well as for adjustment of multiplex equipment and
its assemblies.
the device may be used in-the-fields at a temperature of
t - 10 degree. With to +50 degree. With, as well as in case of relative humidity 9
5. 98% in case of 35ãðàä. S.
the device keeps its parameters after temperature effect from - 50
degree. With to +65 degree. S.
main technical characteristics:
1. Frequency range, kHz 0, 2. 2100
2. Sending-end impedance, Omagh
symmetric input 150; 600
unbalanced input 75
3. Basic error of amplitude-frequency-characteristic measurement, decibel not more + (0, 2À+0, 2),
where - relative amplitude in èçìåð. stop
4. Irregularity of own amplitude-frequency response, decibel not more +0, 2
5. The resolving power by the scale allows to measure of irregularity
from 0, 1 to 20 decibels
6. Capacity, consumption device mains-operated
alternate current 220 V., VA not more 110
7. Device mass, kg 40
8. Overall dimensions, the MM. is not in excess of 500 x 480 x 260 |
