It is important that the mixer be connected directly to the LO's RF Output
connector.
Procedure
1. Connect equipment as shown in Figure 4-9 with the amplifier connected directly to the HP 3585A
50 Ohm input.
The foam pads shown in Figure 4-9 are required to isolate the DUT and
LO from mechanical vibrations which could induce phase noise.
In this procedure, the LO is programmed for +10 dBm. At some points
the LO may indicate an unleveled condition. This is to be expected and
does not affect the phase noise measurement.
2. On the LO, press [INSTRPRESET] [CW][2]
[PEAK].
3. On
press [INSTRPRESET] [CWJ[2]
the DUT,
[PEAK].
4. On the HP 3585A, press INSTR PRESET, CENTER FREQUENCY, 1 MHz, FREQUENCY SPAN, 1
MHz.
5. Switch the HP 3585A AUTO RANGE and REF LVL TRACK off.
6. Allow the equipment to warm up for 1 hour.
