Considerations about Dierences

Spot Measurement

HP 4145A/B can execute a spot measurement by setting both start and stop

of the sweep to the same value, but the HP 4155A/4156A executes the

measurement twice even if you set both start and stop of the sweep to the

same value.

Sweep Steps in Logarithmic Step Mode

Calculation algorithm for primary sweep steps in logarithmic step mode is

slightly dierent between HP 4155A/4156A and HP 4145A/B, so step values

and number of steps may be dierent between HP 4155A/4156A and HP

4145A/B.
