15-8 (E)
SIR-3400H / SIR-3032i / SIR-3032W
15-5. Recording and Playback AUX Analog Data
The recording unit is equipped with the main analog channel of measuring unit and the AUX-2 (IRIG-B)
channel as a sub-analog channel. In this channel, the real-time clock in the unit is mainly synchronized with
the inputted IRIG-B format time code and the IRIG-B time code can be recorded or played back as an analog
signal simultaneously when the main analog data signal is recorded or played back.
Besides the IRIG-B time code, it can be recorded or played back as a general analog signal.
c
The AUX analog data input is AGC-controlled.
15-5-1. Recording and Playback IRIG-B Time Code Signal
Connecting a IRIG-B Time Code Signal
The following IRIG-B time code signal can be connected.
Code : Amplitude modulation code (AC code)
Carrier frequency : 1 kHz
Voltage range : ±1 to ±10 Vpk
Modulation amplitude ratio : 1:3
1 Set the IRIG timecode to On. (See section 8-2-6.)
2 Use a BNC cable (sold separately) to connect the AUX-2 (IRIG-B) IN connector on the rear panel and
the IRIG-B time code signal from an IRIG time code generator.
If necessary, use a BNC cable (sold separately) to connect the AUX-2 (IRIG-B) OUT connector on the
rear panel and IRIG time code reader.
c
When the IRIG timecode is set to Off, it is not handled as an IRIG-B timecode signal.
