1. Specifications and characteristics for Channels
1 and 2 are identical for both common and
separate configurations.
2. Values shown are for X1 attenuator setting.
Multiply all values by 10 (nominal) when using
the X10 attenuator setting.
3. When the 53131A or 53132A are ordered with
the optional rear terminals (Opt. 060), the channel
1 and 2 inputs are active on both front and rear
of the counter. When the 53181A is ordered with
the optional rear terminal, the channel 1 input is
active on both front and rear of the counter. For
this condition, specifications indicated for the rear
connections also apply to the front connections.
4. When optional additional channels are ordered
with Opt. 060, refer to configuration table for
Opt. 060 under ordering info on page 8. There is
no degradation in specifications for this input,
as applicable.
5. Available for all measurements except peak volts.
External arm is referred to as external gate for
some measurements.
