Frequency Accuracy Test - Wavetek 3000 Instruction Manual

EQUIPMENT
Frequency Counter
HP5300B/5303B
PROCEDURE
1 . Set the Signal Generator controls as follows :
4 .3 FREQUENCY ACCURACY TEST
SPECIFICATION
PERFORMANCE TESTS
FREQUENCY selector
050 .000 MHz
MODULATION MODE CW
MODULATION FREQ
(Inactive in CW MODE)
MODULATION FM/AM
(Inactive in CW MODE)
OUTPUT VERNIER
Fully Clockwise
OUTPUT step attenuator +10 dBm
2 .
Connect the Signal Generator RF out connector to the 50
ohm inputof the frequency counter . Set the counter to read
frequency to seven digits .
3 . Observe the
frequency counter reading . Increase the
setting of the Signal Generator FREQUENCY selector in 1 kHz
steps and verify that the frequency counter reading increases
by 1 .00 kHz ±1 count
for each step increase from 1 through
9 kHz .
The foregoing procedure verifies the 1 kHz resolution
specification .
4 .
Repeat the
procedure in step 3 for all other step in-
creases indicated in the table below beginning with the 10
kHz digits .
If the actual counter frequency increase per
step is equal
to the allowable increase per step ±1 count
for each of the steps indicated in the table, place a check
mark in the applicable space on line 1 of the PTR .
Accuracy CW and AM modes
±0 .001% after 15 min .
(Typ ±0 .002% after
2 hours
within 3 months of calibration)
FMxl mode
±(0 .001% +10 kHz)
FMxl00 mode
±(0 .001% +45 kHz)
