Power1401 Top Boxes & expansion

Micro

The standard Power1401 may be expanded in capability by fitting a range of modular top boxes. These expansion boxes make internal connections to the Power1401 motherboard. They require the Power1401 expanded mechanics (can and case) and are unsuitable for end-user installation.

ADC16 : sets of 16 more waveform inputs 4001-3

$2455

The set of waveform input channels may be expanded by adding an ADC16 (4001-3) expansion box with sixteen extra channels, which are mapped onto ADC channels 8-23. Once the Power1401 is told about the extra channels by the installation program, the new ones may be freely used just like the basic set. Software that reads the extra channels will return undefined data values if the waveform expansion box is not installed.

The ADC inputs are of identical design to the ones on the base unit, with an input range of ±5V (optionally ±10V). As on the base unit, there is an option of programmable gain x1, x2, x5 and x10 for 16 waveform inputs (2701PG) or 8 waveform inputs (2701PG8).

PGA16 : sets of 16 more waveform inputs 2701-4

$3460

A similar unit, PGA16 (2701-4), is available with individually programmable gain on each channel, in steps of x1, x2, x5, x10 in the range from x1 to x1000.

Spike2 top-box 2701-9

$2380

In some circumstances, such as in many Spike2 applications, the digital inputs and outputs are heavily used for signals. It is convenient to have more of these connectors available on the front panel as BNCs. The 2701-9 top-box provides six event inputs, mapped onto digital inputs 10-15, together with eight ADC inputs and a pair of DACs, mapped onto ADC 8-15 and DAC 2-3 respectively. The safe working voltage range of the digital inputs is ±10V, and they present an impedance of 100 kOhm.

Signal top-box 2701-5

$2925

The Signal program is often used with many waveform channels. The 2701-5 top-box provides eight more ADC inputs and four more DACs, mapped onto ADC 8-15 and DAC 4-7 respectively, with 2 of the original digital outputs, 2 and 3, and 2 of the DACs all available on BNCs on the front panel.

8 channels of tracking filter with PLL synthesiser

$4860

The PGF8 2701-21 is designed for researchers in vibration analysis and other systems generating periodic signals. It provides eight signal-processing channels plus auxiliary circuits. The heart of each channel is the switched-capacitor filter (SCF) and selectable gain, but there are also options for AC coupling, and simultaneous sample-and-hold (S&H). The channels have individual control of gain level, and individual enabling of the SCF and the AC coupling. The SCF pass frequency and the S&H functions act equally on all channels.

A phase-locked loop (PLL) offers programmable frequency multiplication of a trigger source. This can be very useful when triggering information comes from smoothly-varying systems such as rotating shafts. The front panel provides outputs for DACs 2 and 3.
