F unction: F our indep enden t displa y c hannels 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 mo de, with resp ect to
frequency , on the internal CR T/LCD. Three detector inputs (A, B, and R) accept A C or DC detected signals from detectors
or bridges.
Option 001 has four detector inputs (A, B, C, and R).
Mo dulator Driv e : The analyzer mo dulator driv e output provides the circuitry to driv e the HP 8340 and 8341 synthesized
sw eep ers and the HP 11665B mo dulator. Y ou can turn mo dulator driv e on and o via either the fron t panel or HP-IB. In the
OFF state, the mo dulator driv e signal turns the HP 11665B fully on for minim um insertion loss. The 8360 and 8370
synthesized sw eep ers have the capability of mo dulating signals, so an external mo dulator such as the 11665B is not necessary
when using the 8360/8370 series.
Mark er Accuracy : The marker frequency accuracy is 0.1 PPM of the marker frequency plus the source marker frequency
accuracy .
F requency : 27.778 kHz 612 Hz
Symmetry : 50% 61%
Dynamic Range, Dynamic Accuracy , Absolute P o w er Accuracy : These system sp ecications are dep enden t on the
detector used. The follo wing examples show b oth the HP 85037A/B and the HP 11664A/E detectors. (F or HP 85025 and
HP 85026 sp ecications, refer to their manuals.)
