–HF Option CS Series – Supplemental Specifications
Specifications for the CS units with the –HF frequency range option installed are the same as
the standard CS unit except where noted below.

45 Hz - 2000 Hz
2000 - 5000 Hz (see Note)
Note:
On multi box systems -HF frequency limit is set to 5000 Hz but performance to specification is
guaranteed only to 2000 Hz. Above 2000 Hz, full power may not be available due to amplifier
unbalance. Current measurements accuracy is affected by system interface cable cross talk
above 2000 Hz.
