5. Leveled Sine Wave Generator Flatness 1%, 250 kHz to 50 MHz. The
flatness can be characterized (a chart
made of variations) with the TEKTRONIX
Peak-to-Peak Detector (015-0408-00).
TEKTRONIX SG503 Leveled Sine Wave
Generator installed in a TEKTRONIX
TM500 Series Power Module.
When using the TEKTRONIX SG503 the
following additional accessories are
needed:
Two 50 W coaxial cables, Tektronix Part
No. 012-0482-00.
A 50-to-75 W minimum loss attenuator,
Tektronix Part No. 011-0057-00.
6. Digital (Frequency) Counter Range: 10 kHz to 20 MHz; accuracy,
±0.001%.

Series Power Module.
7. Peak-to-Peak Detector Amplifier Tektronix Part No. 015-0408-00 (includes
one 015-0413-00 Peak-to-Peak Detector
Head). Installed in a TEKTRONIX TM500
Series Power Module.
8. Detector Head Two each, Tektronix Part No.
015-0413-00 for use with TEKTRONIX
Peak-to-Peak Detector Amplifier (item 7).
One Detector Head is supplied with the
Peak-to-Peak Detector.
