The filters are useful for filtering out small common mode signals below 5 Vp-p. To order these filters, order HP E1586 Option 001. -
Page 6: Terminal Block Connections
Figure 1. Connecting the Terminal Panel Custom Length Cable This cable (HP Z2220A Option 050) is available in custom lengths. It is a 16-channel twisted pair cable with each twisted pair individually shielded to provide better quality shielding for longer cable runs. -
Page 7: Using The Terminal Panel For Reference Temperature Measurements
The following explains how to use the Terminal Panel as an isothermal reference panel for thermocouple measurements. This explanation is for connections to an HP E1413C High Speed A/D Converter or an HP E1415A Algorithmic Closed Loop Controller Mounting the HP The Terminal Panel can be mounted in a standard size instrument rack. - Page 8 Connecting One Terminal Panel for Reference Temperature Measurements In this configuration, a single Terminal Panel is used with an HP E1413C/ E1415A to provide up to 32 channels for temperature measurements. Make the following connections on the thermistor terminal block of the Terminal...

Figure 4. Connecting Six Thermistors on Two Panels Using the Option 001 RF Filter The HP E1586 Option 001 Terminal Panel has an additional board that contains the RF Filters. These filters consist of a 3-winding common-mode transformers for each channel. These transformers greatly attenuate common mode signals above 1 kHz. -
Page 10: Analog Inputs Using Two-Wire Cabling
RC filters are provided on the board. Use of the filters decreases the low-frequency Common-mode Rejection to about 90 dB at 60 Hz, and the measurement bandwidth to about 10 kHz for the E1413 or E1415. 10 HP E1586A Rack Mount Terminal Panel... -

This especially the case when low level HP E1413/E1415 analog SCPs are used with the digital I/O SCP. This configuration may make... -
Page 12: Typical Reference Temperature Measurements
Typical Reference Temperature Measurements The following shows how to make reference temperature measurements on the E1586 thermistors using the HP E1413 High Speed A/D Converter or the HP E1415A Algorithmic Closed Loop Controller. The methods to measure the thermistor reference temperature depends on the location of the Terminal Panel. -
Page 13: Measuring Using The Center Thermistor
Measuring Using To measure the center thermistor, select an HP E1413C or E1415A channel as a reference channel. Connect the reference channel’s HI and LO to the the Center center thermistor (thermistor 2) HI-T2S and LO-T2S terminals, Thermistor respectively. These connections are shown in Figure 8 on page 13. -
Page 14: Measuring Using The Left, Center, And Right Thermistors
These connections are shown in Figure 11 on page 16. Use the information in the HP E1414C/E1415A User’s manuals to setup the instruments to make the reference measurements. The following are two examples that measure type K thermocouples. One example uses a single Terminal Panel and the other uses two Terminal Panels. - Page 15 SENS:FUNC:TEMP TC,K,.06,(@103:131,135:163) defines channels for temperature measurements ROUT:SEQ:DEF (@100,103:107,101,108:123,102, 124:131,132,135:139,133,140:155,134,156:163) defines the scan list Note that each reference channel (100, 101, 102, 132, 133, 134) immediately precedes its associated measurement channels in the scan list.
