AFFORDABLE ANALOG TESTING IN A RUGGED, HAND-HELD PACKAGE. ATS 2 Enhanced Audio Test Set The ATS 2 is a full feature audio test set in a portable, hand-held package. The set facilitates the installation and maintenance of leased or dial-up circuits and equipment connected to the public switched networks. Designed to comply with IEEE and Bell specifications, the ATS 2 is capable of performing all basic analog transmission measurements plus Impulse Noise, Signal-to-Noise and P/AR tests. The ATS 2 can also function as a telephone handset on 2- and 4-wire circuits, with dial, hold, talk and listen capabilities. � Menu driven � Impulse Noise and Signal-to-Noise tests � DTMF or pulse dialing � MF dialing optional � Tests to IEEE and Bell specifications S P E C I F I C A T I O N S ATS 2 Enhanced Audio Test Set SEND MODES BACKGROUND NOISE AUTODIAL QUIET TERMINATION 10 to 99 dBm Range: Memory: 10 locations, each capable Signal generator disconnected from 1 dB Resolution: of holding up to 16 digits output ACCURACY Dial method: DTMF or pulse with Output Noise <-80 dBm 20 to 99 dBm: –1 dB optional MF SEND FREQUENCY –2 dB 10 to 20 dBm: DTMF signals: Full supervisory tone set, Range: 50 Hz to 5 kHz C-Message, 3 kHz flat, Filters: GENERAL including A,B,C, and D Resolution: 1 Hz C-Notch INPUT/OUTPUT Accuracy: –0.03% True RMS Detector: Line: 2-wire or 4-wire Direct Entry: Numeric keypad Absolute or relative with Display modes: Connectors: RJ11C modular jack and dual Stepping: –1, 10 and 100 Hz respect to input level miniature phone jack (0.173� Fixed frequencies: 1004 Hz, 2713 Hz and 995 to 1025 Hz >50 dB Notch filter: diameter on 0.312� centers, programmable auxiliary tone rejection mates with ADC PJ777 or Slope tones: 404 Hz, 1004 Hz, and 2804 Hz Loss of tone: <-40 dBm Swtchcraft TT253) 10 seconds per tone SIGNAL TO NOISE 150 volts Auto step: Programmable start, stop, +10 dBm to -40 dBm Signal range: DC blocking Reverse send and receive step size and step duration 10 dBm to 90 dBm Noise range: Normal/Reverse switch: Electronic, 24 ma.
