unction
Four indep endent display channels pro cess signals from the HP 85025, 85026, 11664, or 85037 detectors and the
HP 85020 or 85027 bridges. The analyzer displays the data logarithmically, in single input or ratio mode, with resp ect to
frequency, on the internal CRT/LCD. Three detector inputs (A, B, and R) accept AC or DC detected signals from detectors
or bridges.
Option 001 has four detector inputs (A, B, C, and R).
Modulator Drive
The analyzer modulator drive output provides the circuitry to drive the HP 8340 and 8341 synthesized
sweep ers and the HP 11665B modulator. You can turn modulator drive on and o via either the front panel or HP-IB. In the
OFF state, the modulator drive signal turns the HP 11665B fully on for minimum insertion loss. The 8360 and 8370
synthesized sweep ers have the capability of modulating signals, so an external modulator such as the 11665B is not necessary
when using the 8360/8370 series.
Marker Accuracy
The marker frequency accuracy is 0.1 PPM of the marker frequency plus the source marker frequency
accuracy.
