Z5623A Option H87

Description
Description
The Agilent Technologies Z5623A Option H87 is a 1 GHz to 50 GHz Dual Directional Pulse
Test Set. When connected to the E8364B PNA Series Network Analyzer with Option H08
(Pulse) and H11 (IF access), pulse measurements for both the forward and reverse
parameters from 1 GHz to 50 GHz can be made depending on the PNA and highpass filter.
The Z5623A Option H87 can be configured in many ways. The bypass configuration allows
the user to use the E8364B PNA Series Network Analyzer from 10 MHz to
50 GHz. This mode bypasses the test sets internal 1 GHz to 50 GHz PIN modulator switch.
In the pulse mode the user can configure the test set for their application needs to either
make straight un-conditioned pulse measurements or permit the insertion of high power
amplifiers and other signal conditioning equipment to allow high power measurements at
RF levels up to 20 Watts (+43 dBm) from 10 MHz to 40 GHz and 10 Watts (+40 dBm) from
40 GHz to 50 GHz.
Control of the Z5623A Option H87 Dual Directional pulse test set can be performed either
by GPIB or directly. Both methods control the port 1 and port 2 internal switches and
attenuators. Direct control requires the user to connect to the two 37-pin D-sub connectors
located on the rear panel. Both GPIB and direct control cannot be used simultaneously.
When used in the direct control mode, the test sets front panel LCD indicator may differ
from the user setup.
High power configurations require that attenuators and isolators be connected to the test
ports and receivers to protect the E8364B PNA Series Network Analyzer. The E8364BH85
High Power Configurable PNA Series Network Analyzer when ordered with the Option
H08 and H11 can be used for high power pulse measurement applications. More
information on the setup and configuration of the E8364BH85 PNA Series Network
Analyzer can be found in the Microwave PNA Series High Power Configurable Test Set
Option H85 manual (p/n E8364-90027).
The instrument is shipped from the factory with jumper cables installed on the front panel
in what is called the Shipped Configuration. See Figure 1-11 on page 16.
Two highpass filters are shipped with the Test Set. The filters are used externally. The
filters are used to eliminate video feedthru from the PIN switch. The low frequency filter
(Z5623-80085) allows pulse measurements from 1 GHz and 20 GHz. The second filter
(Z5623-80084) allows pulse measurements between 20 GHz to 50 GHz. See “System Setup”
on page 17.
The pulse test set can be used from 400 MHz to 1 GHz but is not specified. No bandpass or
highpass filters are provided for this range. If pulse measurements below 1 GHz are
required, the user must provide an appropriate highpass filter for that band.
2
Z5623A H87 User’s and Service Guide
Description
If any pulse measurements are required using a frequency band that includes frequencies
above and below 20 GHz, the user must supply a bandpass filter for that band or make two
separate measurements. At this time, there is no filter available to allow pulse
measurements from 1 GHz to greater than 20 GHz. At a minimum there will need to be
separate measurements for 1 GHz to 20 GHz and then 20 GHz to 50 GHz.
Install the instrument so that the ON/OFF switch is readily identifiable and is easily
reached by the operator. The ON/OFF switch or the detachable power cord is the
instrument disconnecting device; it disconnects the mains circuit from the mains supply
before other parts of the instrument. Alternatively, an externally installed switch or circuit
breaker (which is readily identifiable and is easily reached by the operator) may be used as
a disconnecting device.

Video Feedthru
Video Feedthru
Video leakage refers to the spurious signals present at the RF ports of the switch when it is
switched without an RF signal present. Refer to Figure 1-1. These signals arise from the
waveforms generated by the switch driver and, in particular, from the leading edge voltage
spike required for high speed switching of PIN diodes. When measured into a 50 Ω system,
the magnitude of the video leakage can be as much as several volts. The frequency content
is concentrated in the band below 250 MHz, although measurable levels can be observed as
high as several GHz. The magnitude of the video leakage can be reduced significantly by
adding a highpass filter in the RF path Pulse Out to Filter In. Refer to Figure 1-2.
Figure 1-1 illustrates the leading and trailing edges of video feedthru.

Electrostatic Discharge Protection
Electrostatic Discharge Protection
Protection against electrostatic discharge (ESD) is essential while removing assemblies
from or connecting cables to the network analyzer. Static electricity can build up on your
body and can easily damage sensitive internal circuit elements when discharged. Static
discharges too small to be felt can cause permanent damage. To prevent damage to the
instrument:
• always have a grounded, conductive table mat (9300-0797) in front of your test
equipment.
• always wear a grounded wrist strap (9300-1367) with grounding cord (9300-0980),
connected to a grounded conductive table mat, having a 1 MΩ resistor in series with it,
when handling components and assemblies or when making connections.
• always wear a heel strap (9300-1126) when working in an area with a conductive floor.
If you are uncertain about the conductivity of your floor, wear a heel strap.
• always ground yourself before you clean, inspect, or make a connection to a
static-sensitive device or test port. You can, for example, grasp the grounded outer shell
of the test port or cable connector briefly.
• always ground the center conductor of a test cable before making a connection to the
analyzer test port or other static-sensitive device. This can be done as follows:
1. Connect a short (from your calibration kit) to one end of the cable to short the center
conductor to the outer conductor.
2. While wearing a grounded wrist strap, grasp the outer shell of the cable connector.
3. Connect the other end of the cable to the test port and remove the short from the
cable.

Operation Overview
Operation Overview
The Z5623A Option H87 Dual Directional Pulse Test Set can be configured differently for
many applications. Included in this document are four typical configurations:
• Figure 1-11, “Shipped Configuration.”
• Figure 1-12, “System Setup Configuration (similar test set shown).”
• Figure 1-13, “High Power Pulse Forward Direction (similar test set shown).”
• Figure 1-14, “High Power Pulse Dual Direction (similar test set shown).”
• Figure 1-15, “Pulse Dual Direction (similar test set shown).”
NOTE
The internal firmware of the PNA has not been modified for this test set
option. The power levels indicated on the Agilent E8364B may differ
depending on the user configuration that is chosen.
Refer to the configuration diagrams for external component connections and/or operating
constraints when utilizing the high power capability of the Z5623A Option H87 Dual
Directional Pulse Test Set. External components are not supplied with this option other
than those in the Table 1-1 on page 4.
When using the E8364B Series Network Analyzer with Z5623A Option H87 Dual
Directional Pulse Test Set in the bypass or the high power configuration, the PNA
Frequency Offset mode (Option 080) and External R1 (Option 081) must be activated. This
will ensure phase lock and allow R1 and R2 to receive the new reference power levels from
the amplifiers. Refer to Table 1-2 on page 15.
CAUTION
The Z5623A Option H87 is equipped with reference channel attenuators.
These attenuators reduce the RF power to the PNA R1 and R2 receiver ports.
The test set attenuators can be set from 0 to 60 dB in 10 dB steps.
The recommended power levels to the PNA R1 and R2 receiver ports is
–15 dBm. Refer to your PNA specifications to optimize power levels to the
receiver ports.
The PNA Option 016, Receiver Step Attenuators, reduces the power to the
A and B receivers. The A and B maximum attenuator setting is 35 dB. Power
measurements to Test Ports 1 and 2 above +35 dBm will require additional
attenuation. Add the appropriate amount of attenuation that will keep the
coupler arm output power below –15 dBm. Refer to Table 1-2.
CAUTION
14
Hot Switching is not allowed with the Z5623A Option H87 when making high
power measurements or damage to the switch will occur. Hot Switching is the
condition when the internal switch or switches are set to a position for
making high power measurements, and then set to another position without
reducing the power. The maximum power that the switches are allowed to
switch states is +20 dBm.
Z5623A H87 User’s and Service Guide

Controlling the Test Set
Controlling the Test Set
The Z5623A Option H87 is considered a “slave” instrument. A Controller must be used to
control the test set. There are four ways to control the test set:
• The PNA can be used as the controller to talk to the test set over the GPIB.
• A Controller can directly talk to the test set over the GPIB.
• The Parallel port can be used to set the test set.
• Direct control access to the internal switches and attenuators via open collector lines
to ground the input lines.
Commands
As mentioned before, the test set can be controlled in four ways. The first two involve the
use of a separate computer. The third way uses parallel port manually. The fourth control
method uses direct access from two rear panel 37 pin D-Sub connectors.
NOTE
The 37 pin D-Sub jumpers (Z5623-60202) must be attached to the test
sets Port 1 and 2 rear panel direct access connectors for the GPIB and
parallel port commands to work. These connectors are not connected to
the test set when they are shipped.

Controlling the Test Set
Direct Control
The fourth method to control the test set uses the Port 1 and Port 2, 37 pin D-Sub
connectors located on the rear panel. Jumper connectors (Z5623-60202) must not be
attached to allow the user to control the internal switches and attenuators. Refer to
Table 1-5 on page 41 which illustrates the pinout and function for Port 1 and 2.
NOTE
LCD indicator is only valid when the test set is used in control methods;
PNA, Controller, and Parallel. Direct control does not change the LCD
indicator when either the switches or attenuators are repositioned.
Controlling the Switches
Control of the internal switches directly, is provided from the 37 pin D-Sub connector and
can be done in two ways.
• TTL
• Open Collector
The TTL input allows the user independent switch position control by either a low (0) or
high (1). The TTL voltage is 0 or 5 volts. The Figure 1-32 on page 38. The 37 Pin D-Sub
connector illustrates the rear panel input/output configuration for Port 1. Port 2 is
identical to Port 1 but where SW1 is replace by SW4, SW2 is replace by SW5, SW3 is
replace by SW6 on the RF block diagram. Pins 5, 12, 22 are the TTL input pins. Pin 5
controls SW1 or SW4, pin 12 controls SW3 or SW6, and pin 22 controls SW2 or SW5.
The Open Collector inputs allows the user to control a switch position by grounding either
the A (AD) or B (BD) dive input lines for each switch. Only one of these two input lines can
be grounded at any given moment. Recommended is break before making when the input
line position changes. Figure 1-32. The 37 Pin D-Sub connector illustrates the rear panel
input/output configuration for port 1. Port 2 is identical to port 1 but where SW1 is replace
by SW4, SW2 is replace by SW5, SW3 is replace by SW6 on the RF block diagram. Pins
(1,2), (8,9), and (25,26) are the A and B drives input pins. Pins 1, 2 control SW1 or SW4,
pins 8, 9 control SW3 or SW6, and pins 25, 26 control SW2 or SW5.
Switch Indicators
The internal switch positions can be read only when used in the Direct Control method.
A switch position can be read by either a low (0) or high (1) on the A (AI) or B (BI) indicator
lines. The voltage is either 0 or 5 volts depending on the switch position. Low (0) indicates
disabled, and high (1) indicates enabled. Figure 1-32 illustrates the rear panel
input/output configuration for port 1. Port 2 is identical to port 1 but where SW1 is replace
by SW4, SW2 is replace by SW5, SW3 is replace by SW6 on the RF block diagram. Pins
(3,4), (10,11), and (23,24) are the A and B indicator output pins. Pins 3, 4 indicate SW1 or
SW4 position, pins 10, 11 indicate SW3 or SW6 position, and pins 23, 24 indicate SW2 or
SW5 position.
Figure 1-33 on page 38 illustrates how each switch is configured.

Switch Indicator Function
The 87222E is set to the A or B Position. Refer to Table 1-6 on page 42, Switch Indicator
Voltages for Test Set Modes. When the switch is set to the A position the Indicator
Common is connected, completing the A Indicator path. The 21 VDC connected to the
Indicator Common is connected to ground by two resistors (30 kΩ and 10 kΩ). The Position
A and B Indicators have independent 10 kΩ resistors to ground. The measured voltage
from Position A Indicator to ground is approximately 5 Volts and the Position B Indicator
will measure 0 Volts. When the switch is set to Position B, the Indicator common is
connected. Measuring the voltage from Position B Indicator to ground will measure
approximately 5 Volts and the A indicator will measure 0 Volts.
Example 1 A Indicator Position Connected

•
•
•

•
Resistance Indicator Common in a connected path = 40 kΩ
Resistance between the Indicator Common and Position A when connected = 30 kΩ
Resistance between Position A and ground = 10 kΩ
Resistance between the Indicator Common and Position B when connected = OPEN
Resistance between Position B and ground = 10 kΩ
I = V/R = 21 V/40 kΩ = 0.525 mA
Voltage drop across 30 kΩ resistor: V = I×R = 0.525 mA×30 kΩ = 15.75 Volts
Voltage drop across 10 kΩ resistor: V = I×R = 0.525 mA×10 kΩ = Position A indicator to
ground = 5.25 Volts
In that the Position B switch to the Indicator Common is open, only the 10 kΩ resistor
ground is connected providing a drop-down on the Position B Indicator pin, effectively
grounding it.

Controlling the Attenuators
Controlling the attenuators are identical to the Switch Open Collector control method.
Figure 1-32 on page 38 illustrates the rear panel input/output configuration for Port 1. Port
2 is identical to port 1, but ANT1 is replace by ANT2. Pins 13-18 control the attenuator.
Like the switch open collector lines, brake before making the attenuator bypass or select
setting changes.
CAUTION
Always break-before-make a selection when using the Open Collector control
inputs for the switches and attenuators. Failure to do so can damage the
internal switches or attenuators.
CAUTION
Make rear panel Direct Control connections while the test set is off. Ensure
that all inputs are OFF before making any connection. Turn off the test set
before removing the connector jumper. Failure to do so can damage the
internal switches or attenuators.

Making High Power Measurements With Option H87
The Z5623A Option H87 and PNA with Options 014, 016, 080, 081, and UNL or H85 can be
configured to measure high power devices. This ability is useful if the required power for
the device under test is greater than the analyzer can provide, or if the maximum output
power from an amplifier under test exceeds safe input limits for a test set and analyzer.
This section describes how to set up the analyzer to perform high power measurements.
Setup
1. Turn off all of the equipment. Be sure that the jumpers between the PNA and test sets
RCVR 1, RCVR 2 and CPLR THRU are disconnected at this time. This will protect the
PNA from damage.
2. Connect the PNA jumpers for Port 1 and 2 SOURCE OUT and RCVR IN connectors.
3. Connect the Z5623A Option H87 to the PNA, refer to Figure 1-36. Contingent on your
application set up, not all pulse pattern generators may be required as shown in this
figure.
Figure 1-36
Setup Configuration (similar test set shown)

Making High Power Measurements With Option H87
4. If the Z5623A Option H87 Test Set is in the Shipped mode configuration (all the
jumpers are still on) remove the jumper between AMP OUT and AMP IN connectors on
the front panel for Port 1. This can also be done for Port 2 if high power measurements
are necessary for the reverse parameters of a device under test (DUT). Two booster
amplifiers are required for both forward and reverse measurements. Refer to
Figure 1-37, “Connect Booster Amplifier (similar test set shown).”
5. Place four terminations on J1-J4 on the rear panel for AMP 1 and 2.
6. Verify that the Booster Amplifier is turned off at this time.
7. Connect the Booster Amplifier RF INPUT connector to the Port 1 AMP OUT connector
on the front panel of the Z5623A Option H87.
8. Remove the jumper on the Z5623A Option H87 between SOURCE OUT and CPLR IN.
Place an isolator or attenuator between the SOURCE OUT and CPLR IN on the port 2
side.

Determining Power Levels
Before continuing, save this state and set it up as the User Preset key. The User Preset
Conditions can be found in the PNA Series Network Analyzer’s help menu.
1. Press [Menu/Dialog] and tab to Help. Select Network Analyzer Help. Type in User
Preset, this will describe how to setup a User Preset. The final state should be saved
as the User Preset to avoid an over power condition from the factory preset.
To find the User Preset:
2. Press [Menu/Dialog] and tab to System. Scroll down to User Preset. Select User Preset
Enable and press Save, then OK. This will save the current state as User Preset.
3. Turn on the analyzer and decrease the power level to –20 dBm by pressing
[Menu/Dialog] and tab to Channel. In the drop-down menu select Power. Scroll to Port
Selection and enter [–20]. Select Port Power Coupled to ensure that Ports 1 and 2
power levels are the same. Uncoupled ports should be used when adjusting the S12
power level or when Port 1 has a very low power level in comparison to Port 2.
NOTE
Frequency Offset mode (Option 080) and External R1 (Option 081) must be
activated when using the analyzer in a high power configuration. This will ensure
phase lock and allow the R1 and R2 to receive the new reference power levels from
the amplifiers.
• Press [Menu/Dialog] and tab to Channel. In the drop-down menu select
Frequency Offset and turn on the Frequency Offset Mode. In the Offset
Setting set the Offset to [0].
• Press [Menu/Dialog] and tab to Channel. In the drop-down menu select
Test Set. Select the External R1 Loop in the R1 Input Path window.
4. Set the Z5623A Option H87 Test Set so that the external booster amplifier is in the RF
path. Refer to “Controlling the Test Set” on page 28 to set the external Booster
Amplifier to be engaged in the RF path.
5. Turn on the booster amplifier.
6. Measure the output power from the booster amplifier RF Output using a power meter
and sensor.
NOTE
Additional attenuation may have to be added between the coupler and the
power meter, depending on the power used.
7. Verify the gain of the Booster Amplifier(s). For example, if the analyzer’s output power
level was set to –20 dBm and the output power measured from the open end of the
coupler was –5 dBm, the gain of the booster amplifier would be +15 dB.
Z5623A H87 User’s and Service Guide
45
Making High Power Measurements With Option H87
8. Verify that the power measured in the previous steps is within the acceptable limits
(less than +43 dBm for the AMP IN port). The maximum power level between 40 GHz
and 50 GHz is +40 dBm.
9. Turn off the booster amplifier.
10. Estimate the maximum power level that will be needed to force the DUT into
compression. Acceptable limits are less than +43 dBm for the AMP IN port.
The maximum power level between 40 GHz and 50 GHz is less than +40 dBm.
CAUTION
Do not command the test set to engage or disengage the amplifier from the
Port 1 RF path while the amplifier is on. This can damage the internal RF
switches in the test set.
11. Verify that the Booster Amplifier is turned off.
12. Connect the Booster Amplifier RF OUTPUT connector to the Port 1 AMP IN connector
on the front panel of the Z5623A Option H87.
13. Turn on the Booster Amplifier.
14. Using a high power meter and sensor, measure the output power from the test sets
RCVR R1 port.
15. Turn off the Booster Amplifier.
16. Estimate the maximum power level that will be needed to force the DUT into
compression.

Z5623A H87 User’s and Service Guide
Making High Power Measurements With Option H87
Selecting Power Ranges and Attenuator Settings
1. Select a power range that will not exceed the maximum estimated power level, but will
force the DUT into compression. For example, if your Booster Amplifier has a gain of
+15 dB and the DUT will compress if supplied with +15 dBm, then you would adjust the
analyzer’s output power not to exceed 0 dBm. This can be done by setting the
Attenuator Control to 10 dB by pressing Power, under Attenuator Control, clear Auto
and enter [10] into the entry area. In the “Port Selection” area, the Port Power Coupled
can be checked to ensure that Port 1 and 2 power levels are the same, or clear if Port 1
and 2 power level requirements are different.
2. Estimate the maximum amount of gain that could be provided by the DUT and as a
result, the maximum amount of power that could be received by Test Port 2 when the
DUT is in compression. For example, if a DUT with a maximum gain of +10 dB receives
an input of +10 dBm, then the maximum amount of power that could be received by
Test Port 2 is +20 dBm. An isolator or attenuator may be required depending on the
amount of power at Test Port 2. An isolator is placed between the CPLR IN and
SOURCE OUT to protect the test set and the PNA.
3. Calculate the amount of attenuation needed between the analyzer's coupler and
receiver so that you do not exceed the optimum receiver power level of –15 dBm.
Refer to your PNA specifications to optimize power levels to the receiver ports.
It will be necessary to take the following into consideration:
• Power measured at the test sets RCVR R1 OUT = –2 dBm.
• Estimated compression power = –2 dBm.
• The optimum PNA receiver power level = –15 dBm.
Attenuation Equations:
4. Set the internal Z5623A Option H87 Test Set RCVR R1 step attenuator to the value
calculated below (rounding off to the highest 10 dB step). Refer to “Controlling the Test
Set” on page 28 to set the Attenuator for RCVR R1 OUT path.
With the previous points in mind, the amount of attenuation can be calculated from the
following equations:
Attenuator RCVR R1 Setting = – 2dBm – ( – 15 dBm ) = 13 dBm
RCVR R1 Attenuator Value = 20
5. Turn on the Booster Amplifier.
6. Measure the output power from the test sets RCVR R1 using a high power meter
and sensor.
7. Verify that the power measured in the previous step is within the acceptable limits
(–15 dbm at the RCVR R1 OUT).
Z5623A H87 User’s and Service Guide
47
Making High Power Measurements With Option H87
8. Measure the output power from the test sets CPLR THRU port using a high power
meter and sensor.
9. Turn off the Booster Amplifier.
10. Verify that the power measured in the previous step is within the acceptable limits
(less than +43 dBm at the CPLR THRU port). The maximum power level between
40 GHz and 50 GHz is less than +40 dBm.
11. Calculate the amount of attenuation needed between the analyzer's coupler and
receivers so that you do not exceed the optimum receiver power level of –15 dBm.
It will be necessary to take the following into consideration:
• Receiver A will be coupled to the analyzer RF path that could receive power reflections
as high as +10 dBm.
• Receiver B will be coupled to the analyzer RF path that could receive a maximum of
+20 dBm from the DUT.
• Analyzer coupler loss is –13 dB.
• The optimum receiver power level is –15 dBm.
12. Set the internal step attenuator to the value calculated below (rounding off to the
highest 5 dB step). Setting the receiver attenuation will set the internal attenuation.
Press [Menu/Dialog] then tab to Channel. In the drop-down menu select Power, under
Receiver Attenuation set Receiver A to [10] and Receiver B to [20]. Power levels
greater than +35 dBm will require additional attenuation between Port 2, access ports
CPLR ARM and RCVR B IN.
With the previous points in mind, the amount of attenuation can be calculated from the
following equations:
10 dBm – 13 dBm – ( – 15 dBm )
Attenuator A = 12 dBm
Reciver Attenuator B = 20 dBm – 13 dBm – ( – 15 dBm )
Attenuator B = 22 dBm
Reciver Attenuator A =

5. Turn on the DUT and measure the S21 gain of the amplifier under test to confirm the
proper operation of the measurement test setup.
6. Continue with any other high power measurements.
NOTE
Ratio measurements, such as gain, will be correctly displayed. However,
the displayed absolute power levels on the analyzer will not be correct.
To correctly interpret power levels and the gain of the booster amplifier,
the attenuator setting must be taken into consideration.
If no calibration has been performed or if the instrument is in an un-calibrated state,
the following must be taken into consideration when interpreting the measured data:
• The value of attenuation added to receiver A and B.
• The R channel reference level supplied from the test set.
• Protection of the internal parts for the test set and PNA.
This procedure can be repeated to setup the reverse high power configuration.

Test Set Internal Configurations
Test Set Internal Configurations
The Z5623A Option H87 can be internally configured to allow the user to configure it for
different application requirements. In this section we will show the test sets internal
configurations. The Test Sets Port 1 side is a mirror image of the Port 2 side. Both sides are
independent of each other.
For simplicity the Port 1 side will be used for the following examples.
There are four basic mode configurations:
• Bypass
• High Power
• Pulse
• Pulse High Power
• Amplifier Terminate
Bypass
The bypass mode sets the Test Set’s internal switches so that the SOURCE IN port thru
path connects directly to the CPLR THRU port. This allows you to use the PNA in a
normal operation. The test port and R1 reference power at the PNA will be reduced due to
the loss of the test set. Figure 1-40 illustrates the main signal flow through the test set
Port 1 side, which is identical to the Port 2 side.

Procedure
To test the performance of the Z5623A Option H87 this document assumes that the user is
familiar with the necessary equipment. The PNA USB keyboard and mouse will be
necessary to enter GPIB commands and to read the trace data. Measurements can be
made easier by setting up Markers with search, tracking and search domain user states for
each of the frequency bands.
Using the PNA as the controller to issue commands to the Z5623A Option H87 Test Set can
be found in “Controlling the Test Set” on page 28.
General S-Parameters are used to characterize the connection paths of the test set. Both
reflection and transmission measurements are required. These measurements are made
with the E8364B, 2.4 mm cal kit and RF cables. Power Output and Pulse Shape are not
measured to re-verify the Z5623A Option H87 Test Set.
A Full 2-Port SLOT (Short, Load, Open, Thru) Calibration should be performed on the
PNA at the ends of the RF cables. The Isolation must not be omitted. The calibration
should be performed at the following settings shown in Table 1-8.
