Channel Multiplexing
One of the more unique features of the Berkeley Nucleonics pulse generators is the ability to combine the timing of any or all channels together and output them out of any of the output BNCs. The multiplexing function (MUX) can be set through remote communications via a computer or from the front panel of most units.
Selectable Clock Reference
The Model 577 offers additional inputs and outputs for external clock synchronizing. Specify your input/output reference frequency (10 MHz to 100 MHz). Synchronize with the Mode Lock Oscillator of a laser or phase lock multiple units with one clock.
Flexible Gating Options
The Model 577 is packed with gating options for almost any setup. You may gate with a channel or on any input. You may gate individual channels or gate all. Gate immediately (output inhibit) or gate after a pulse (pulse inhibit).
External Trigger Options
Select channels for internal/external triggering, or free-run. Triggered channels have flexible output choices: single pulse, burst at its clock rate, continuous pulse train or a series of on/off pulses (duty cycle). Contact us for custom wave trains or modes.
Individual Rates
Each channel can have individual channel rates (either T0 or any of the other channels…).
Auto-Save
Forgot to save your settings? The Model 577 stores your setup configurations while powering down. Recall is automatic on power-up.
Dual Input Panel Connectors
The Model 577 offers two inputs for triggering or gating. You may specify electrical or optical input signals, and configure any trigger/gate combination. Use Trigger #2 to disable a triggered pulse train.
Front Panel High Voltage
Our modular architecture offers expanded functionality on user-selected front panel outputs. We offer a front panel High Voltage option (adjustable from 35V, 200 mV steps) on 2, 4, 6, or all 8 channels.
Front Panel Optical
Many applications benefit from optical signals. For noisy environments or communications applications, we offer an LED output stage at the front panel. This modular option can be configured for 2, 4, 6, or 8 outputs at 820nm or 1300nm.
Combined Output Types
The outputs are configured in modules and output types are combined in pairs. Thus one may select optical, standard electrical, or high voltage electrical in pairs for their instrument. For example, an 8-channel unit may have optical, standard electrical, and high voltage outputs all on one instrument. Custom or additional output modules may be added as the need arises. See our helpful Order Chart for all option configurations.
Field Programmability
The instrument can now have functions upgraded in the field, such as a special or custom feature upgrade via a fully programmable FPGA.
Custom Output Modes
Custom Modules such as the TZ-50 give users an expanded list of capabilities with the Model 577. One example is our TZ50 option, which provides customers a TTL signal into 50 Ω expanded.
Negative Delay
Use the convenient negative delay feature to reference one channel with respect to another channel in positive or negative time increments. By allowing a channel to reference another channel as its trigger, you can synchronize the channels with respect to each other.
Note: The Negative Delay cannot trigger a channel before your initial trigger. It is intended to complement the channel referencing option.
