Specications describe the instrument's warranted preformance. Supplementary
performance characteristics describe the instrument's non-warranted typical
performance.
Because of the modular nature of the instrument, these performance
specications apply only to this module.You should insert these pages into the
appropriate section of the manual.

Supplementary Performance Characteristics
Internal Digital Modulation
You can select internal modulation frequencies of 270HZ, 1kHz, or 2kHz. All
outputs are pulse shaped, with a duty cycle of 50%.
Output Attenuation
The output can be attenuated from 0 to 6dB, in steps of 0.1dB.
Stability
The value of the long term CW-stability doubles with just one minute warmup
time (source enabled).
