19. Frequency and Sensitivity Check - 500 MHz to 18 GHz
a. Performance Check
CAUTION
Do not exceed +25 dBm peak of input power at the N type
connector (500 MHz to 18 GHz), SMA connector for model
5343A. Damage to the internal sampler may result.
NOTE
When the input signal level to the high frequency input
connector exceeds approximately +5 dBm, each digit in the
display becomes a minus sign (-) to indicate overload.
(1) Connect signal generator RF Output to TI N type input. (Use APC 3.5 male
connector with collar for model 5343A).
(2) Set 10 Hz - 500 MHz/500 MHz - 18 GHz (10 Hz - 500 MHz/500 MHz - 26.5
GHz for model 5343A) switch to 500 MHz - 18 GHz (500 MHz - 26.5 GHz for model
5343A).
(3) Press FREQ SHIFT (blue) and RESOLUTION 1 Hz pushbuttons.
(4) Set signal generator frequency to 500 MHz and level output to -25 dBm (-33 dBm for
model 5343A). TI will display a stable indication of applied frequency.
(5) Adjust signal generator frequency from 500 MHz to 12.4 GHz. TI will display a
stable indication of applied frequency.
(6) Set signal generator frequency to 12.4 GHz and level output to -20 dBm (-28 dBm for
model 5343A). TI will display a stable indication of the applied frequency.
(7) Adjust signal generator frequency from 12.4 to 18 GHz. TI will display a stable
indication of applied frequency.
b. Adjustments. No adjustments can be made.
20. Power Supply
NOTE
Do not perform power supply check if all other parameters are
within tolerance.
a. Performance Check. Connect multimeter HI to -5.2 V TEST POINT (fig. 3) and
LO to chassis ground. If multimeter does not indicate between -5.1 and -5.25 V dc, perform
b below.
