The Low Distortion Oscillator:
A current controlled, state-variable true sine wave oscillator incorporating a fast AGC circuit.  Distortion components are typically 0.1% 2nd and 0.05% 3rd which are low order and not audible making the TS2 useful in making listening tests where a function generator would generate undesirable, audible side effects.  Full frequency sweeps can be made from 20Hz - 20kHz in a single range. These units have no amplitude changes over the entire frequency range. 

• Frequency range:
  - 10Hz - 30kHz
• Accuracy: ± 0.1dB from 20Hz - 20kHz.
• Output impedance: 50 ohm unbalanced. Optional balanced available.
• Adjustable output level: -70dBv to +18dBv ref: (0.775V)
• Maximum output level: +18dBv @ 2k ohm or greater, +16.5dBm @ 600 ohms.
• Distortion: < 0.3% THD

The Frequency Counter:
The frequency counter is internally connected to the internal oscillator and displays the oscillator frequency until a signal is plugged into the input connector. It then displays the frequency of the input signal.  The frequency counter is disabled below 40dB to avoid induced count errors. Below 10KHz the counter updates mice a second. Above 10KHz it updates ten times per second. This unique combination of Frequency Counter and Audio Oscillator affords absolute precision in setting frequencies.

• Frequency response: 1Hz-99.99kHz
• Input impedance: >100k ohms (electronically balanced).
• Input level: -40dBv to +24dBv ref: (0.775V)

The dB Meter:
The dB meter is a wideband average responding AC voltmeter. The circuit output is electronically converted to dB for display. Direct reading dB greatly simplifies alignment procedures.  The logarithmic nature of decibels eliminate the need for range switches.  A reference level of "0dB" is factory set for 0.775v which can be user adjusted +10dB with a rear panel control.

• Meter Range: -50dBv to +24dBv ref: (0.775V)
• Accuracy:
  - ±0.1dB from 20Hz - 20kHz @ 0dBv
  - ±1.5dB from 20Hz -20kHz @ 50dBv
• Adjustable zero reference: -10dBv to +8dBv (rear panel adjustment)
