The equipment has been designed with the objective<br />
of providing a range of parameters as<br />
wide as possible, enabling many different types<br />
of measurement. The time schole of 100 ns to<br />
1 s, a resolution of about 1 °/ 0 (corresponding to<br />
100 channels), its facility of continuous manitoring<br />
- ali ore valuable features suiting the<br />
equipment to very wide applications in the<br />
measurements of stochastic signals. The equipment<br />
is a signal analyser ernplaying 100 digital<br />
channels, a storage capacity of 20 bits/ channel,<br />
performing aU computations simultaneously<br />
with the measurement. The basic as·<br />
sembly does not include a result display, but<br />
it can be attached to any conventional type of<br />
oscilloscope or XV plotter. Furthermore, the<br />
principel signals can be obtained from connectors.<br />
The resuhs can be read out at any frequene-y<br />
even during the measurement. ln addition<br />
to the conventional integreting-type averaging<br />
(single analysis), "forgetting" type integration<br />
(continuous monitoring) is also feasible. Both<br />
the number of averagings and the " forgetting"<br />
time constant ore variable over a wide range.<br />
The equipment can be used for the onolysis of<br />
continuous signals (AC or DC) and pulses. The<br />
width of its time channels can be selected between<br />
100 ns and 1 s (in correlation modes);<br />
thus it is equally suitable for the investigatien<br />
of very fast and very slow processes. ln amplitude<br />
analyses, the maximum sampling freque n<br />
ey is 5 kHz (otherwise 0.5 M Hz). The f unction<br />
generator provides digitaily generated sin, cos,<br />
pseudo-random and sawtooth sionals with<br />
frequencies adjustable over wide limits. The<br />
time functions of the basic assembly in multichannel<br />
signal averaging and correlation modes<br />
e-an be studied by aid of the Fourier transforrner<br />
in the frequency range, too. For a better<br />
i'llustration, the number of frequency pointscan<br />
be increased. Thus, tagether with the cycle time,<br />
the frequency resolütion can be varied over<br />
wide limits (from 1.25 mHz to 100 kHz). Focil1-<br />
ties ore provided for using time w indows other<br />
then the square-form, vis. multiplication by<br />
Honning and Bartlett weighting function. The<br />
real or the imaginary ports of the functions<br />
within the particulor range can be fo rrned in<br />
succession. Like in the basic a ssembly, the data<br />
outputs deliver analog as weil as d igita l signals<br />
moreover, the analog Y output can be switched<br />
over to logarithmic display, too. The Manitor<br />
unit performs mainly ancillary functions -visual<br />
observation of signals, the estimation of their<br />
values, setting the test setup, facilitating a servicing<br />
and handfing of peripherals (e. g. the use<br />
of Z modulation at peak searching}. Plugged in<br />
alternatively, the M anitor and the D igital Interface<br />
will take over the manitoring function of<br />
the power supply. IM PORTANTI The Manitor is<br />
suitable for "off·crate" functioning, too, only a<br />
power supply of +5,8 V/3,5 A is required. The<br />
Digital Interface enables the variaus functions<br />
(recorded by the basic assembly) and, in expanded<br />
configuration, the frequency spectra<br />
(provided by the Fourier transformer) to be displayed<br />
digitaily or recorded on o tape punch,<br />
o printer or teletype - of course, either for o<br />
given point o r for a ny arbitrary section.<br />
