Announcement · Panther · STAR Sync Box
128 phase-synchronized channels. One Panther system.
With the STAR Sync Box, up to 16 eight-channel Panther chassis run as one phase-synchronized system: 128 input channels and up to six drive outputs. That extends what Panther can do in MISO control, MIMO control and vibration analysis.
| System | Up to |
|---|---|
| STAR Sync Boxes | 2, cascaded |
| Panther chassis | 16 |
| Channels per chassis | 8 |
| Input channels | 128 |
| Drive outputs (DACs) | 6 |
| Applications | MISO · MIMO · analysis |
PHASE-SYNCHRONIZED · Every channel on every chassis, as one system.
Why it matters
Bigger articles need more channels, and more channels need one timebase
Large structures, multi-shaker rigs and modal surveys all ask for more measurement points than one chassis holds. Adding channels is only useful if every one of them is measured at the same instant: a phase error between chassis shows up as a false mode, a wrong transfer function, or a control error the loop can't explain.
more points on the article
Large-structure testing
Monitor, limit and abort channels across the whole article, not just at the control point.
more drives, more sensors
Multi-exciter rigs
Up to six drive outputs, with the response channels that degree-of-freedom transforms and limit protection need.
more points in the survey
Vibration and modal analysis
Dense accelerometer layouts measured in one pass, with phase you can trust from the first chassis to the last.
The system
Sixteen chassis, one phase-synchronized Panther
Each STAR Sync Box connects one master Panther chassis and eight slaves. A second STAR Sync Box cascades from one of the first box's slave ports, adding eight more slaves: one master and fifteen slaves, 16 chassis and 128 channels acquiring as a single system on Panther's single DAQ clock.

What it extends
MISO, MIMO and vibration analysis
The STAR Sync Box doesn't change how Panther controls or analyzes. It gives every application more synchronized channels to work with.
| Application | What more synchronized channels give you |
|---|---|
| MISO control | One drive, with control, limit, monitor and abort channels spread across a large article or fixture, all measured on the same timebase. |
| MIMO control | Up to six drive outputs, the number a six-degree-of-freedom configuration uses, with room for the sensors that DOF transforms, limiting and monitoring need. |
| Vibration analysis | More measurement points per run for operating response, transfer functions and STAR modal surveys, so large structures can be covered in fewer setups. |
Grow with your programs
Start at 8 channels. Grow to 128.
Panther expands in 8-channel chassis, so a lab can buy for today's tests and add chassis as programs grow. Every chassis added stays phase-synchronous with the rest.
Sixteen chassis is the configuration Spectral Dynamics has tested. The architecture can cascade further; talk to your sales representative about larger systems.
| Panther chassis | Input channels |
|---|---|
| 1 | 8 |
| 2 | 16 |
| 4 | 32 |
| 8 | 64 |
| 9, one STAR Sync Box (1 master + 8 slaves) | 72 |
| 16, two cascaded STAR Sync Boxes | 128 |
Every chassis
The same Panther front end, 16 times over
- 24-bit ADC with greater than 110 dB dynamic range.
- 262,144 samples/s per channel, simultaneous.
- Phase match ±1.0° to 100 kHz, within and between units.
- Channel crosstalk below −100 dB.
- IEPE and TEDS (IEEE 1451.4), 8 gain ranges, auto-ranging.
- 20-bit DAC outputs, ±12 V peak.
A multi-channel system is only as good as the phase coherence of its front end. That is what makes 128 channels across 16 chassis useful rather than just large.
Questions
Frequently asked
How many channels can one Panther system have?
Each STAR Sync Box connects one master Panther chassis and eight slaves. Cascading a second STAR Sync Box from one of the first box's slave ports gives 16 eight-channel chassis, 128 phase-synchronized input channels, which is the configuration Spectral Dynamics has tested. The architecture can cascade further; talk to your sales representative about larger systems.
How many drive outputs does a STAR Sync Box system support?
Up to six DACs, for MISO control and for multi-exciter MIMO control.
Which Panther applications benefit?
MISO control, MIMO control and vibration analysis. Each application gets more synchronized channels to work with; how it controls and analyzes is unchanged.
Do I have to buy all 16 chassis at once?
No. Panther expands in 8-channel chassis, so a system can start small and grow, with every added chassis phase-synchronous with the rest. Talk to your sales representative for configuration details.
