# CFG253 Tektronix Function Generator Used

**Additional Features:**

-   Frequency range: 1.0 Hz to 3 MHz in 7 ranges
-   Square, Triangle and Sine Waves; TTL Output
-   20 dB Attenuator
-   Internal or External Frequency Sweep
-   Variable Duty Cycle
-   Variable Symmetry (20 to 80%)

The Tektronix CFG253 has output bandwidth of 1.0 Hz to 3 MHz. Function generators produce sine, square and triangle waves and TTL signals for testing amplifiers, filters and digital circuits. Sweep function can be controlled internally or with an external signal. Duty cycle, DC offset, sweep rate, sweep width and amplitude are all operator controlled.
