Specifications and Characteristics
N2830/1/2A Probe Amplifier Specifications and Characteristics
The characteristics listed in the Table 19 are mainly determined by the
N2830/1/2A probe amplifiers.
NOTE
All entries are characteristics unless otherwise noted. Bandwidth and DC input resistance (R
se
and R
diff
) are the only specifications.
