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).

Refer to the Table 3 on page 6 for a list of equipment needed in addition to the E8247C and

E8257C/D Option H30 being tested:

Step 1. Set the RF Source power level to –10 dBm and frequency to 6 GHz.

Step 2. Connect the RF Source to the E8247C and E8257C/D Option H30 rear panel

RF Upconverter Input, using an RF cable and adapters.

Press: [FREQUENCY] > MORE, MORE > UPC ON/OFF (to activate mode)

An audible click should be heard from the E8247C and E8257C/D Option H30 as

the transfer switch switches the upconverter mixer LO to the coupler output and

the mixer RF out to the 1E1 step attenuator’s input.

Step 3. For instruments with Option 540 set the instrument to upconverter mode, set

power level to +8 dBm and CW frequency to 40 GHz. Verify that a 46 GHz signal

appears on the spectrum analyzer when in upconverter mode and is not present

when in standard synthesizer mode. The level of the upconverter IF signal

(6 GHz + 40 GHz = 46 GHz) is nominally –28 dBm.

For instruments with Option 520 set the instrument to the upconverter mode, set

power level to +8 dBm and CW frequency to 20 GHz. Verify on the spectrum

analyzer that a 26 GHz signal appears when in upconverter mode and is not

present when in standard synthesizer mode. The level of the upconverter IF

signal (6 GHz + 20 GHz = 26 GHz) is nominally –28 dBm. Since this is a

functional test only, measurement uncertainty is not taken into account. This

verifies the switch path and mixer are functioning.
