Powerscope II 881A

The 881A Powerscope II is an updated version of the 881 Powerscope II.

This model has a wider bandwidth, new attenuator and time base switches and improved specifications. It incorporates five vertical amplifiers, four wide band differential channels and a 50MHz single ended channel.
The new differential amplifiers are now direct reading from 20mV to 200V/div on all channels with 30MHz bandwidth from 200mV/div and 20MHz from 20mV to 100mV/div.
The rise time of the combined amplifier and the P91, 10:1 probe is typically less than 10ns. This is ideal for switch mode power supplies and, together with the high common mode rejection of the amplifiers, enables direct on-line measurements to be made accurately and safely.
A multiplier can be selected to display CH 1 x CH 2 over the entire sensitivity range with a bandwidth of DC to 12MHz. With voltage applied to one channel and a voltage proportional to current on the other, a direct measurement of instantaneous power is available.
Phase measurement to within 1° can be made from 15Hz to over 2kHz in single or multiphase circuits. The zero reference can be selected from any channel or the input AC, where it is detected to within 1° of zero cross over at line frequency.
