Fluke 203A Distribution Amplifier. 12 channels with 5 filled. The 203A Distribution Amplifier provides an economical method of distributing reference frequencies to many remote locations, such as separate areas of a lab.
1 MHz input and 12 discrete output channels.
Each output channel level individually adjustable.
Accepts 1MHz input frequencies and 12 output amplifiers then provide output frequencies.
Acceptable input levels: 0.5 to 5.0 V rms (input level adjustment for each channel located on rear-panel); input impedance of 50-ohms.
Each output level is continuously adjustable from 0.5 to 4.0 V rms (into 50-ohms).
Short term stability is <1x10E-11 (standard deviation for a 1 s averaging time at 1MHz).
Bandwidth is rated at <3% of input frequency for 3 dB down and 15% for 30 dB down.
BNC Type input and output connectors.
