Hewlett Packard 3325B Shown
Agilent 3325B is a generator/waveform
synthesizer with frequency accuracy, resolution, and stability that are ideal
for applications such as crystal filter test, multiplexed communication system
testing, clock/timing simulation and audio frequency system testing.
Exceptionally linear triangles and ramp signals are produced
with synthesized accuracy and stability for applications such as VCO testing or
process control. The dc-to-21 MHz frequency range (sine) makes the 3325B ideal
for high-performance video system testing.
Pure sine waves or high quality squarewaves can be combined with
up to ±5V of DC offset to interface with biased circuits or for stimulus in
digital environments. In modulation applications, let the Agilent 3325B provide
the carrier for a modulation source, or use the internal modulation source to
get modulated signals from the 3325B alone.
The HP3325B frequency accuracy is determined by a precision frequency-reference
and can be set with a resolution of 1 uHz. It has up to -65dBc harmonic and
-70dBc spurious levels for precision measurements. The phase of the output
signal can be precisely controlled +-719.9 deg with 0.1 deg resolution, and
multiple HP 3325B's can be locked together for multi-phase applications.
Function Generator Versatility
Precision squarewaves to 10.999,999 MHz have 20 ns rise times with synthesizer
accuracy and precision. Triangle and ramp waveshapes are also available with
.05% linearity up to 10.999,999 kHz. DC and phase offset can be added to these
waveshapes. The modulation source can be used as an arbitrary function generator
via HP-IB, providing user-defined waveshapes. These features make the HP 3325B
one of the most versatile sources for bench or ATE system applications.
Save-recall memory includes 10 non-volatile memory locations, for simple and
rapid access to frequently used test setups.
The enhanced feature set of the HP 3325B includes 100-segment discrete sweep
capability which allows arbitrarily defined multi-segment linear or stepped
sweeps and tone sequences. This compliments its linear and log, phase continuous
Internal Modulation Source
A built-in programmable modulation source provides sine, square and arbitrary
waveshapes for internal amplitude or phase modulation, or for use as a second
source. In addition, a rear panel sync output provides a TTL compatible dc to
50MHz signal with 1uHz resolution for use as a precision, high resolution clock
signal, and extended frequency coverage.
ATE systems Compatibility
All functions, including frequency, amplitude, phase, modulation, sweep and
waveshapes are programmable via HP-IB or RS232 interface. The HP 3325B is fully
compatible in form, fit and function, with the HP 3325A. All HP-IB programs
written for the HP3325A are fully compatible with the HP3325B. An isolated
interface, combined with floating outputs and inputs assures trouble free
operation in a systems environment. The main output can be switched to the rear
panel by a simple front panel keystroke, or under program control for optimum
