{{EndSpecs}}


With the input sensitivity set to 10 mV/div and above, the 454A has a vertical bandwidth of 150 MHz.
It is possible to cascade the CH1/CH2 input amplifiers to obtain a sensitivity of 1 mV/Div (454A: 400 μV/div) at a bandwidth of 33 MHz.
At 5 mV/div it is 100 MHz, and at 2 mV/div it is 50 MHz.  


It is possible to cascade the channel-1 and channel-2 input amplifiers to obtain a sensitivity of 400 μV/div.
The 454 has two ±12 V probe power outputs for [[P6045]] probes.
In that configuration, the vertical bandwidth is 33 MHz.


The 454 weighs 29 pounds and consumes about 130 watts.

The 454 came in several different modifications that were indicated on the field on the front plate directly below the "454" lettering, left of the serial number field. Known modifications are
* MOD163D
* MOD210N - [[P6047]] accessory probes come in 6 ft variant with extra accessories.
