Tektronix Launches Two New 6½-digit DMM and DAQ systems : DMM6500 And DAQ6510

Tektronix, a US-based company, has introduced two new Keithley 6½-digit models to its line of Digital Multimeters (DMMs) and data-acquisition systems: The new DMM6500 DMM and also the new DAQ6510 data-acquisition system. The company has also upgraded their Kickstart measurement software to version 2.0.

Keithley has long been a dominant provider in the 6½-digit DMM market. With the DMM6500 and DAQ6510, the company looks forward to strengthening its position further. Both of these new instruments use the same touchscreen UI (with pinch gesture) first unveiled with the company’s 7½-digit DMM7510.

With a base price of $1140 (same as previous models), the DMM6500 hits a sweet spot for bench and production measurements. In addition to its 6½ inch display, the DMM6500 also features a 16-bit, 1 Msample/s digitizer and can display voltage and current waveforms over time. It can store up to 7 million readings in internal memory.

Like its previous models, the DMM6500 is also expandable to ten channels. It uses the same expansion cards as models in the 2000 series DMMs. The DMM also maintains software compatibility with Keithley’s 2000 series models, minimizing software changes. It also emulates software commands for the now obsolete but still in use HP/Agilent/Keysight 34401A.

Measurement ranges:

  • DCV and ACV: 100 nV to 1000 V (750 VAC) with 0.0025% 1-year DCV accuracy
  • Resistance: 1 µΩ to 100 MΩ
  • DC Current: 10 pA to 10 A, AC Current: 100 pA to 10A
  • Temperature: -200°C to 1820°C
  • Capacitance: 0.1 pF to 100 µF
  • Digitize Voltage: 10 µV to 1000 V
  • Digitize Current: 10 nA to 10 A
  • Maximum measurement reading rate: 20,600 readings/s

Communications and channel expansion:

  • Interfaces: LAN LXI and USB-TMC standard. GPIB with digital I/O ($225), RS-232 with digital I/O ($200), or TSP-Link with digital I/O ($200).
  • Multichannel measurement capacity: 10 channels with two card options (10 channels voltage/current ($628) or 9 channel temperature/general-purpose inputs ($700)

DAQ6510:

Based on the DMM6500, the DAQ6510 ($1750 system only, $2230 with 20-channel scanner card) support up to 80 channels using two 40-channel cards. Keithley offers twelve switch modules, which are the same as used in the 2700-series data-acquisition DMMs. Scanning speed is 800 channels/s across multiple systems connected through Keithley’s TSK Link. The GPIB and RS-232 interface modules are also supported.

Haasoscope – Cheap, flexible, data acquisition for all!

Haasoscope is the first open-source, open-hardware, flexible, small, cheap, oscilloscope and data-acquisition board. You can use the stock firmware for basic oscilloscope functionality, or modify the firmware to customize what the Haasoscope does.

Preliminary features and specifications:

  • 4 x 100 MHz, 8-bit ADC channels with BNC cable inputs
  • Altera Max10 FPGA with 8k logic elements and 387kb of memory
  • Reprogram firmware over JTAG, or on the fly, with free Quartus II software
  • Readout over serial-to-USB at 1.5 Mb/s, about 20 Hz for 4 channels of 512 samples each
  • USB powered, (or other 5 V input, switchable), ~1.2 Watt
  • 8 x spare digital I/O
  • 9 x additional analog I/O with 1 MHz (1MSPS combined) at 12 bits
  • 7 x programmable LEDs, and a reset button
