Model 3336A/B/C Performance Tests
4-8. PERFORMANCE TEST RECORD.
4-9. A Performance Test Record is located at the end of this section to help you consolidate
the test results, -hp- recommends that copies of the Performance Test Record be used.
Copies of the Performance Test Record can be made at any time without written permission
from Hewlett-Packard.
4-10. PERFORMANCE TESTS.
4-11. The following Performance Tests have been specifically developed to test the -hp-
3336:
Paragraph No.
Frequency Accuracy 4-12
Absolute Amplitude Accuracy 4-14
Amplitude Flatness 4-16
Attenuator Accuracy 4-18
Phase Increment Accuracy 4-20
On Carrier Return Loss 4-22
Output Balance 4-25
Harmonic Distortion 4-27
Spurious Signals 4-29
Amplitude Modulation Envelope Distortion 4-31
Phase Modulation Linearity 4-33

Integrated Phase Noise 4-37
4-12. Frequency Accuracy.
4-13. The frequency accuracy of the 3336 is not specified. However, the aging rate is. A
standard 3336 should pass this test, one year after the frequency has been calibrated. A 3336
with Option 004 should pass this test, one week after the frequency has been calibrated.
Specification: (Aging Rate)
+5 x 10 —6 per year (20 to 30°C)
+5 x 10 —8 per week, Option 004
Required Equipment:
Electronic Counter -hp- Model 5328A
with Option 010
75 ohm Feedthru Termination -hp- Model 11094B
a. Connect the equipment as shown in Figure 4-1.
b.
Set
the
3336
(DUT)
output
amplitude
to
+
7.00
dBm
(75
ohm
output).
Set
the
output
frequency
to
20
MHz.
If
the
3336
has
Option
004,
disconnect
the
adapter
between
the
10
MHz OVEN
Output
and
the
EXT
REF
Input.
c.
Set
the
electronic
counter
to
measure
frequency
with
.1
Hz
resolution.
(On
the
-hp-
5328A,
the
counter
will
overflow,
however,
the
accuracy
of
the
measurement
is
not
affected.
