H70
70 MHz IF Output
Upgrade
E440xB Option H70 provides an analog 70 MHz IF Output to the
rear panel of the ESA by down-converting the 321.4 MHz IF
signal. The70 MHz IF is always “ON” while the ESA is powered
up.
For all conversion loss parameters listed below, the attenuator
setting is 0 dB. In highband, the preselector center routine must
be performed to achieve the conversion loss listed below. If
applicable, when Option 1DS (100 kHz to 3 GHz Preamp) is on,
there will be a 28 dB to 30 dB of gain in the 70 MHz IF Output on
the rear panel of the ESA. With the Preamp ON the conversion
loss outlined below will be +22 dB.
While performing the “Align All” routine on the ESA, the 70
MHz IF Output will be corrupted due to the systems variable gain
circuit stepping through the alignment routine.
There are no flatness corrections for the 70 MHz IF Out.
In all other respects this instrument is identical to the standard
instrument specifications.
B72 Enhanced Memory Upgrade Option B72 provides 2 SIMMS which increases the analyzer’s
RAM to 32 MBytes and its flash or data storage memory to 16
MBytes (8 MBytes of which are available to the user for data
storage and measurement personalities). Note, this option is
standard in analyzers with prefixes of US4144 and MY4144 and
above.
UE2 Firmware Upgrade Kit Option UE2 provides the most current ESA spectrum analyzer
firmware on 3-1/2 inch floppy disks.
