E8247C and E8257C\D Option H30 User’s and Service Guide Supplement 1
Description The Option H30 adds a mixer and coax switch to enable the E8247C or the E8257C/D to upconvert a RF signal (input is provided on the rear panel) to a higher frequency which will be the sum and difference of the RF input signal and frequency set on the E8247C or E8257C/D. The coaxial switch allows the E8247C or E8257C/D with Option H30 to be switched from standard synthesizer mode to upconverter mode. This allows the E8247C to be used as a standard source instrument, as well as an upconverter.
Nominal Performance Characteristics Nominal values indicate expected performance or describe product performance that is useful in the application of the product, but is not covered by the product warranty.

Operation and Performance Verification Documentation Conventions The following key conventions are used throughout this document. • [HARDKEYS] are labeled front panel keys. • SOFTKEYS are unlabeled keys whose function is indicated on the instrument display. Option H30 Operation (520 or 540) To use the E8247C and E8257C/D Option H30 as a standard instrument, refer to the standard User’s Guide.
Performance Verification The E8247C and E8257C/D Option H30 functionality can be verified using the following equipment and methods: The E8247C and E8257C/D Option H30 must first meet standard product specifications with the exception that the power output may be degraded by up to 2.0 dBm. (Subtract 2.0 dBm from the Option 1E1 output power specification).
Troubleshooting If there is no signal a problem has occurred. First check the equipment setup, verifying outputs on the sources and connections. Refer to Figure 4 through Figure 7 . Verify that the E8247C and E8257C/D Option H30 Upconverter switch is working: MID Board or Coaxial Switch The following procedure will aid in determining whether the MID board (E8251-60089) or the coax switch (87222E) is functional. Step 1. Select upconverter mode on/off, then listen for the coax switch to click.
Upconverter Mixer The following procedure will aid in determining if the upconverter mixer is functional: CAUTION Possible damage may occur if RF upconverter input levels exceed 20 dBm or if reverse power is applied at the RF output connector. First verify all cable configurations are correct before applying a signal to the instrument. The RF step attenuator cable to the coax switch is functional if the instrument operates as a standard synthesizer.
