Product Description
Hewlett-Packard 86602B RF Section – Option 002, 1-1300 MHz with Phase Modulation
This used HP 86602B is an RF plug-in section designed for the Hewlett-Packard 8660-series Synthesized Signal Generator System . This unit includes Option 002, which adds phase modulation capability – a key differentiator from standard units .
About the HP 86602B RF Section
The 86602B RF Section provides precisely tuned RF output frequencies over the 1 to 1300 MHz range with 1 Hz frequency resolution . It is used with an Option 100 8660-series mainframe (Frequency Extension Module installed) . Frequencies from 200 kHz to 1 MHz can also be generated with some degradation in amplitude leveling and related specifications .

About Option 002 – Phase Modulation
The front panel of Option 002 instruments is marked with the term “PHASE MODULATION” after the frequency range . This option includes circuits to provide phase modulation capability, enabling more versatile signal generation for testing communications systems and components .
System Requirements & Compatibility
-
Mainframe Compatibility: Requires 8660-series mainframe with Option 100 (Frequency Extension Module Model 11661A installed)
-
Auxiliary Section: Requires a modulation plug-in (e.g., 86631B, 86632B) for complete operation
-
Phase Modulation Modules: Option 002 RF Sections are required when using dedicated phase modulation modules like the 86634A or 86635A
-
8660A/B Compatibility Note: Option 002 RF Sections may have compatibility requirements with early mainframes (serial prefixes 1349A and below) – consult manual
Condition:
SOLD AS IS
USED – SHOWS NORMAL LAB WEAR (rack marks, scuffs, cosmetic wear)
UNTESTED – RF OUTPUT/PHASE MODULATION FUNCTION NOT VERIFIED
NO MAINFRAME INCLUDED (requires 8660-series mainframe)
NO MODULATION PLUG-IN INCLUDED (requires separate modulation section)
POWER SUPPLIED VIA MAINFRAME ONLY
PICTURE MAY NOT MATCH PRODUCT
⚠ CRITICAL NOTE: This is a plug-in section only and requires an HP 8660-series mainframe with Option 100 (Frequency Extension Module) for operation . It also requires a modulation plug-in (e.g., 86631B, 86632B) for complete signal generation capability . Option 002 is confirmed by the “PHASE MODULATION” marking on the front panel .
Potential Applications:
-
Replacement RF section for existing 8660 systems
-
Communications system testing requiring phase modulation
-
Radar and telemetry applications
-
Research and development laboratories
-
Vintage HP test equipment restoration
-
Parts salvage for 8660-series systems
