User Manual 3153
Getting Started 1-3
Note:
Field upgrades for larger memory banks are not available.
Aside from the differences above, all channels have the same frequency
bandwidth, the same output power and the same operational flexibility
and performance.
The Model 3153 is completely digital. There are no analog functions
resident in its hardware circuits. Data has to be downloaded to the
instrument for it to start generating waveforms. The instrument can
generate nine different standard functions such as sine wave, square
wave plus seven other functions. Each time that a standard function is
required, the instrument has to calculate its coordinates and place them
in the waveform memory. Therefore, every time a standard function is
recalled, minimal time is required for the controller to compute the
function and load its data to the waveform memory.
The frequency accuracy of the output waveform is determined by the
clock reference. Using CLK10 as the reference oscillator provides 100
ppm accuracy and stability over time and temperature. If higher
accuracy and/or stability are required, one may connect one’s own
reference oscillator to a front panel input and use this input as the
reference for the three sample clock generators of the 3153. Frequency
may be is programmed with up to 9 digits, so using an external reference
is recommended, if you intend to utilize the full resolution provided by
the instrument.
Output amplitude for each of the channels may be programmed
separately within the range of 20 mV to 20 Vp-p into an open circuit, and
10 mV to 10 V into 50
Ω
. Amplitude and offsets are programmed with 4
digits of resolution.
Besides its normal continuous mode, the Model 3153 responds to a
variety of trigger sources. The output waveform may be gated, triggered,
or may generate a counted burst of waveforms. A built-in trigger
generator with a programmable period can be used as a replacement of
an external trigger source. As was discussed above, the channels can
operate separately from each other. Each channel has its own set of
output and input connectors. The trigger inputs are separate for each
channel as well. In master-slave configuration, the trigger input of the
slave channels are disabled and channel 1 trigger input is the only
active trigger input. The VXIbus TTLTrg0 through TTLTrg4 and
ECLTrg0 may be routed to any channel. However, in master-slave
configuration, active trigger signal is that which is applied to channel 1.
The Model 3153 generates arbitrary waveforms with 12 bits of vertical
resolution. Any waveform it generates must first be downloaded to
waveform memory.
