Quadrature BNC Connector Yes Yes The DS1002 audio output is through 2xLR Video Output connectors. These connectors can be config- ured in a variety of ways (depending on sys- tem), including: mono, SAP, stereo right and left, both right or both left. The DS1001A also has a 4.5 MHz intercarrier output for driving an external aural modulation monitor. Remote Programming The DS1000 Series supports remote program- ming via either RS-232 or RS-485 at 9600 baud. Most front-panel controls can be accessed via the port. The CSS50 software can automatically control the DS1000 Series, as well as a 2714/15 Spectrum Analyzer. 2 Video Networking Monitoring • RF • www.tektronix.com/video_audio Television Demodulators DS1000 Series Remote television broadcast monitoring solution with VM700T series video measurement set DS1001A/DS1001G (M/N) DS1002 (B/G) Video Section Video Outputs Two BNC connectors Two BNC connectors 4.5 MHz Intercarrier Two BNC connectors None DS1000 Series Input and Output Baseband Video Video Signal Output (all) 1 V baseband video 1 V baseband video p-p p-p (GCR 1 channel only) VM700T 1 Video Signal-to-noise* >50 dB (NTC7-weighted) >50 dB (unified-weighted) Frequency Response ±0.7 dB, 100 kHz to 3.58 MHz ±0.7 dB, 100 kHz (18°C to 26°C) ±2 dB, 3.58 MHz to to 4.43 MHz 4.1 MHz (typical) Group Delay ±50 ns, 100 kHz to 3.58 MHz ±60 ns, 100 kHz Sound Trap Off to 4.43 MHz Group Delay Reference FCC Curve B The DS1000 series television demodulator can be part Sound Trap On of a total television monitoring system when coupled Differential Gain (all) <1.5% <1.5% with a VM700T video measurement set.
