DESCRIPTION

1-17. The HP Model 8 340A Synthesized Sweeper
is a broadband, analog sweep, frequency synthe­
sizer with versatile modulation and output power
control.
1-18. The 8340A generates synthesized output
frequencies from 10 MHz to 26.5 GHz. Frequency
resolution from 1 Hz at 10 Mhz to 4 Hz at 26.5
GHz is available. Frequency accuracy is a function
of the internal time base accuracy or an external
frequency standard. Harmonically-related signals
are at least 35 dB below the carrier (-35 dBc) and
nonharmonically-related spurious outputs are at
least -5 5 dBc.
1-19. The 8340A features AM modulation rates
from de to 100 kHz. Pulse modulation circuitry
allows rise and fall times of <25 nanoseconds, an
ON/OFF ratio of> 80 dB, and will pass pulses as
narrow as 100 nanoseconds.
1-20. Maximum calibrated output power from
the APC 3.5 RF OUTPUT connector is
dBm from 10 MHz to 20 GHz and
from 20 GHz to 26.5 GHz. The lowest output
power available in all bands is -110 dBm. Dis­
played power resolution is 0.05 dB. A Power
Sweep function provides the ability to sweep
power up to 40 dB.
1-21. The 8340A is capable of generating a true
analog sweep across its entire 10 MHz to 26.5 GHz
frequency range. Additionally, a synthesized
sweep mode allows precision analog sweeps as
narrow as 100 Hz.
1-22. Additional features include fi v e calibrated
frequency markers and various sweep modes ori­
ented around stored marker positions. The ability
to Save and Recall up to 9 front panel settings also
allows an Alternate Sweep function.
1-23. The front panel ENTRY DISPLAY shows
the current active function and its appropriate
values. Data entry is quickly accomplished
through· the use of the numeric keyboard, step
keys, or RPG (Rotary Pulse Generator) control.
All front panel functions, except the lines switch,
are programmable through the HP-IB bus.
1-24. Many serviceability features have also
been incorporated in the 8340A. An internal SELF
TEST is run each time the instrument is turned on
or when the front panel INSTR PRESET key is
pressed. Front panel diagnostic routines are
accessible to aid in fault detection and isolation.
Additional detailed information on troubleshoot­
ing and repair procedures is included in Appendix
A, In Case of Difficulty, in this volume. This infor­
mation is also included in Section VIII, Service, in
Volumes 3 and 4.
