Description

Model 577-8C / 8-Channel Digital Delay Generator (250ps Delay & Width Resolution & 200pS Internal Channel to
Channel Jitter) RS-232, USB Standard

Model 577-8C  provides multi-channel 250 ps-resolution timing, delaying, gating, pulsing and synchronizing functions at an attractive price. In addition to the traditional digital delay and pulse generator modes, there are many practical modes of operation and features. For usefulness and value – there is nothing comparable.

Each channel provides both delays and widths – a 4-channel Model 577 provides the same delay and width functionality of competitive 8-channel units. The Model 577 is available in 4 and 8 channel configurations, with optional Ethernet, High Voltage and Dual Input Trigger options.

This Digital Delay/Pulse Generator, representing our finest in precision timing, provides precise delays and widths with 250 pS resolution for times up to 1000 seconds. Low jitter, with both internal clocks (50pS) and using an external trigger (800pS) gives users the timing needed to control many devices. This is particularly useful where several pulses or gate signals need to be delayed and timed with respect to each other or with a common trigger. You may even use one channel as a trigger reference for other channels, locking the timing delays when needed. There is much to learn about the Model 577, which offers much more, including a clock-divider, independent channel triggering, independent amplitudes/channel, delay and width control, and a LabVIEW 8 driver. Give us a call we are happy to discuss your applications.

NEW FEATURES IN THE MODEL 577:

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 handy 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 TZ-50 option, which provides customers a TTL signal into 50 ohms expanded.

Negative Delay

Use the handy 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 that Negative Delay cannot trigger a channel before your initial trigger. It is intended to compliment the channel referencing option.
