◈ Introduction
TC-1400A is an audio equipment tester developed for performance tests of microphones and speakers.
TC-1400A bears both signal generator and signal analyzer inside. The generator can send a tone signal within 100 Hz ~ 10 kHz range by 1 Hz span
and the analyzer can measure frequency, tone level, and distortion (SNR, SINAD, THD, etc.) of the signal at the same time.

◈ Benefits and Key Features
※ Signal generator and signal analyzer in one device.
※ Simple and simultaneous audio performance tests: frequency, tone level, SNR, THD, SINAD.
※ Switchable 4 port inputs (LINE IN L/R, MIC 1/2), switchable 4 port outputs (LINE OUT L/R, SPK 1/2).
※ Microphone circuit inside.
- Just connect a microphone to MIC 1/2 port without an extra circuit.
※ Additional functionality available by equipping optional modules to DB25 port for specialized tests (ex: ear jack hook test, input impedance shift).
※ Convenient remote control.
- Remote control through ETHERNET port (TCP/IP) or USB Port (USB To Serial) GPIB.
※ Compact size for portability and easy set-up
※ Analysis software
- GUI for port setting, generator/analyzer control, signal analysis in time/frequency domains.
- Easy preservation of graphical data as a file (.csv).
※ Audio Sweep
※ A part of custom audio equipment testing solution
- With affiliated products such as Audio Shield Box, fixture, speaker, microphone, and automating software of Tescom, we can provide an optimal testing solution as a whole rather than just one equipment.
