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 TS1 & 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
..... TS1RMX only: 10Hz - 27kHz
Accuracy: ± 0.1dB from 20Hz - 20kHz.
Output impedance: 50 ohm unbalanced. Optional balanced available.
....... TS1RMX only: 63.2 ohms (balanced).
Adjustable output level: -70dBv to +18dBv ref: (0.775V)
............... TS1RMX only: -60dBv to +24dBv ref: (0.775V)
Maximum output level: +18dBv @ 2k ohm or greater, +16.5dBm @ 600 ohms.
............... TS1RMX only: +24dBv @ 2k ohm or greater, +22dBm @ 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. This unique combination allows 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 converted to dB for display. Direct reading dB greatly simplifies alignment procedures.
Meter Range:.. -50dBv to +24dBv ref: (0.775V)
.. TS1RMX only: -70dBv 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)

TS2 only - Impedance Meter:
The impedance meter measures complex impedance in ohms. It allows the user to set up and validate studio equipment, measure components, develope equipment, test loudspeakers and enclosures and to measure and validate distributed loudspeaker systems.
Range: 0 - 999 ohms with 0.1 ohm resolution (standard)
............ 0 - 9999 ohms with 1 ohm resolution above 999 ohms (optional 10k version)
Accuracy: ±5%
