Programmable Audio Test System

Unspecified 

SMPTE and DIN Tests

Lower Frequency Range: 50 Hz to 250 Hz.

Upper Frequency Range: Usable from 3 kHz

to 163.8 kHz.

Level Ratio Range: 1:1 to 4:1 (lower:upper)

Residual IMD: See System Specifications.

CCIF Difference Frequency Test

Frequency Range: Usable from 4 kHz to

163.8 kHz.

Difference Frequency Range: 80 Hz to 1 kHz.

Residual IMD: See System Specifications.

All Functions

Display: 3 1/2 digits resolution at

approximately 3 readings per second.

Detection: Average or true RMS for

waveforms with crest factors ≤3. Option 02

replaces average detector with quasi-peak

detector complying with CCIR

Recommendation 468-2 and DIN 45405.

Filters: 400 Hz High Pass: -3 dB at 400 Hz

±5%; 18 dB/octave slope, at least 40 dB

rejection at 60 Hz.

80 kHz Low Pass: -3 dB at 80 kHz ±5%;

18 dB/octave slope.

Audio Bandpass: -3 dB at 22.4 Hz and

22.4 kHz, both ±5%. Complies with CCIR

Recommendation 468-2 and DIN 45405.

“A” Weighting: Meets specifications for

Type 1 sound level meters (ANSI S1.4,

IEC Recommendation 179). Option 02

replaces “A” weighting filter with CCIR

weighting filter complying with CCIR

Recommendation 468-2 and DIN 45405.

EXT: Allows connection of external filters.

Input Type: Balanced (full differential).

Input Impedance: 100 kΩ ±2%, each side

to ground.

Maximum Input: 300 Vpk, 200 V RMS

either side to ground or differentially.

Fully protected on all ranges.

Common-Mode Rejection: ≥50 dB at 50

or 60 Hz. Typically ≥40 dB to 300 kHz.

Front Panel Signals

Input Monitor: Provides constant amplitude

version of signal applied to input. Output

voltage 1 V RMS ±10% for input signals

greater than 50 mV. Source impedance 1

kΩ ±5%.

Function Output: Provides a scaled sample

of selected function signal. Output voltage

1 V RMS ±3% for 1000 count display.

Source impedance 1 kΩ ±5%.

Auxiliary Input: Provides input to detector

circuit when EXT FILTER button is depressed.

Sensitivity 1 V RMS ±3% = 1000 count

display. Impedance 100 kΩ ±5%, ac coupled.

Rear Interface Signals

Duplicates of all front-panel inputs and

outputs are provided to allow external filter

connections or oscilloscope monitoring

within same mainframe without exposed

cables. Detector outputs with specified

scale factors also available to drive analog

chart recorders, storage oscilloscopes, or

similar devices.

Power Requirements

Occupies two compartments of a

TM 5000 mainframe.
