All functions can be calculated and displayed
from the stored basic measurement data. The
measurement setup used Is stored together
with the data
POSTPROCESSING:
Equalize: Calculates the complex ratio of the
measured and stored Transfer Function. Ap-
plies also to Impulse Response
A-Weighting: Autospectrum, Coherent and
Non-coherent Output Power and Sound In-
tensity can be A-weighted in any frequency
span
Integration and Differentiation: Frequency
domain functions: Single and double division
or multiplication with jw can be selected.
Time domain functions: Single or double Inte-
grated or differentiated functions obtained by
inverse transformation from the frequency
domain
Delay Compensation: For compensating
Frequency Response phase measurements
for system delays. Adjustable from - T to
T.

Bow-Tie Correction: Correlation Functions
can be displayed with or without bow-tie
correction
Cepstrum Littering: Shortpass or longpass
with selectable length
SYSTEM ACCURACY:
Frequency Response: ± 0,4 dB at filter cen-
tres with DC coupling
Amplitude Linearity: ± 0,1 dB or ± 0,01% of
maximum Input voltage, whichever Is greater,
measured In Autospectrum with at least 32
Independent averages, In the presence of an-
other In-band signal not less than 20 dB below
max. Input
Dynamic Range:
>
75 dB, for Autospectrum
.
with at least 32 independent averages. Noise,
distortion, and spurious signals at least 75 dB
below max. Input voltage
.Minimum Detectable Signal Level: 1JLV
Frequency Accuracy and Stability: 0,01%
without warm-up, (no adjustment necessary)
OPERATION:
Measurement Setup: 10 complete user-de-
fined measurement setups can be saved and
recalled from a non-volatile memory. Mea-
surement setup parameters can be changed
before or during a measurement. Additionally
10 factory-defined complete measurement
setups are saved In ROM
Display Setup: 10 complete user-defined
display setups can be saved and recalled
from a non-volatile memory. Display setup
parameters can be changed before, during or
after a measurement. Additionally 1 0 factory-
defined complete display setups are saved In
ROM
Parameter Entry: Via Increment/decrement
controls, continuously variable speed field
entry control, or numeric keypad
Auto Scale: Display autoscale to maximize
the area of the CRT used. The largest numer-
lc value In the function on the display Is auto-
matically selected as new Y -full scale
Averaging Control: Start, Proceed, Stop
Start: Clears the average accumulator and
starts an average
Stop: Stops the averaging process or rejects
an estimate in manual accept
Proceed: Continues an average without
clearing the average accumulator or accepts
an estimate In manual accept
